The Samsung Galaxy Z Fold 4 is now getting an astrophotography mode through the updated Expert RAW app.
The mode was first introduced on the Galaxy S22 series.
It enables you to take high-quality, long-exposure images of the night sky.
If you have the foldable phone, you should be able to use the astrophotography mode with Samsung’s updated Expert RAW app. For those unfamiliar with Expert RAW, it’s Samsung’s advanced camera app for Galaxy phones. You can download it from the Galaxy Store. The app will inform you that an update is available when you open it. The Galaxy Z Fold 4 supports astrophotography with Expert RAW version 2.0.09.1.
Samsung introduced astrophotography mode with the Galaxy S22 series and then brought it over to the Galaxy S23 series. The feature enables you to take high-quality, long-exposure images of the night sky, provided you have a clear view. The constellation overlay function also helps locate nearby stars and celestial bodies.
According to Samsung, astrophotography follows a six-step process — celestial search, composition settings, camera settings, continuous shooting, compositing, and post-editing.
The company is also expected to roll it out to older phones like the Galaxy Z Fold 3, Z Fold 2, and the Galaxy S20 series.
For those in the northern hemisphere, May is the last month until September when the night sky gets properly dark after sunset. It also brings your best last chance to grab a post-sunset photo of Venus high in the sky and, if you time it precisely, close to a slender crescent moon.
• Make sure you’re using the best lenses for astrophotography
Add some wonderful deep-sky objects, the rise of a full ‘Flower Moon’ – eclipsed from some parts of the world – and good views of the Milky Way, and May 2023 will be a great month to get outside with your camera.
Friday, May 05: a full ‘Flower Moon Eclipse’
A full moon is always a monthly highlight for anyone interested in photographing the night sky, but for some parts of the world, it’s accompanied by something rarer. From Africa, Asia and Australia, but also from parts of Eastern Europe, a penumbral lunar eclipse will occur.
This is when the full moon drifts through Earth’s fuzzy outer shadow for a few hours, which causes it to be significantly duller. It’s not as photogenic as a total lunar eclipse – also called a ‘Blood Moon’ – but the lack of brightness does make it a great time to photograph the full moon without the usual glare.
This lunar eclipse will be inaccessible to many, but wherever you are you can capture the rising full moon. Just check your local moonrise time and be on time at a location with a good view low to the eastern horizon. Don’t forget to bring a 70-300mm lens, a tripod and a remote shutter release. Here’s more on how to photograph the full moon.
Saturday, May 06: Eta-Aquarid meteor shower
Best seen just after midnight early on May 06 is this annual meteor shower caused by Halley’s comet. Dust and debris left in the inner solar system by the most famous periodic comet will strike Earth’s atmosphere to cause a maximum of 60 ‘shooting stars’ per hour, according to the American Meteor Society. The Eta-Aquarids is a stream of material that Earth busts through between April 19 and May 28 each year, but it’s the peak night that brings the most activity.
The ‘shooting stars’ will appear to come from the constellation Aquarius, but can appear anywhere in the night sky, so a wide-angle lens is a must. Photographers in the southern hemisphere will get the most shots of meteors, though since the moon will be full across the world, only the very brightest ‘shooting stars’ will shine through. Find out more on how to photograph a meteor shower.
Friday, May 12: May’s ‘Milky Way window’ opens
Last Quarter (or Third Quarter) Moon today sees our satellite half-lit and rising after midnight. It will rise about 50 minutes later each night for the next week, which leaves the skies dark for deep-sky astrophotography and, for the first time in 2023 for those in the northern hemisphere, good views of the brighter core of the arc of the Milky Way.
Look for its soft glow close to the eastern horizon after dark during May. Your latitude makes a huge difference, so make sure you check the best time to see the Milky Way where you are.
Wednesday, May 17: Occultation of Jupiter by the moon
A 6% waning crescent moon will, just before dawn today in the eastern sky, move across to block Jupiter – though only as seen from Canada, the contiguous US, Mexico, Greenland, northern Scandinavia and the northern UK. Here are the details and timings for that event, which can be customized to your location. The shot to go for is Jupiter’s disc just alongside the crescent.
If you’re not in the path of this occultation then a shot of a very slim crescent moon very close to Jupiter will also be something special. Even for those in the path, the re-emergence of Jupiter will take place in a much brighter sky, so it will not only be more difficult but won’t be as picturesque because it will be next to the dark limb of the moon. You must take care not to point a camera lens anywhere near the sun. To be safe, avoid the optical viewfinder, relying only on the electronic screen on the back of your camera.
Saturday, May 20: Deep-sky astrophotography
With the moon roughly between the Earth and the sun, it’s completely absent from the night sky. This makes tonight (and, practically speaking the few nights on either side) a great time for a long session outside capturing faint nebula, star clusters and galaxies. Here is a handful that pass roughly overhead (so in the darkest patch of the night sky) this month…
Sunday, May 21 to Tuesday, May 23: A crescent moon and Venus
Nightscapers will love May 21’s alignment of a 6%-lit crescent moon with Venus (and a more distant Mars) in the post-sunset night sky. The following evening the 11% crescent moon will be even closer to Venus while on May 23 an 18%-lit crescent moon will sit gloriously between Venus and Mars, with the stars of Gemini just above.
Each evening it will be possible to capture ‘Earthshine’ on the moon – sunlight reflected from Earth onto the lunar limb. Wide-angle lenses in particular are good at picking-up Earthshine without any special settings. Just be sure to capture in raw to make post-processing easier. Here you can learn when to photograph the moon.
Wide-angle shot of the month: the Eta-Aquarids meteor shower
‘Shooting stars’ move fast, and during the Eta-Aquarids meteor shower they move super-fast. Achieving a whopping 148,000 mph as they strike Earth’s atmosphere, according to NASA, you’ll need a camera taking long exposures for several hours if you’re to catch any of the predicted bright ‘trains’ – material that glows for a second or so in the meteor’s wake.
It’s important to have a wide-angle lens (14-16mm works best), a tripod, a fast aperture (f/2.8 or lower) and a high ISO setting (ISO800 or more if you have a full-frame camera). Take a series of 30-second exposures for a few hours from midnight and you’ll stand the best chance of capturing some ‘shooting stars’.
However, you will need a clear sky, so keep an eye on weather forecasts, though with the full moon coinciding with the Eta-Aquarids meteor shower this year there’s no need to go looking for a dark sky – they don’t exist during this moon phase. This is a project for your backyard!

This astrophotography for beginners guide is designed to help you get started photographing the night sky. The subject of astrophotography — taking photographs of the night sky — is such a broad one with so many subcategories that it’s hard to know where to begin. In this guide, we’ve concentrated our knowledge into a beginner’s guide to astrophotography that will equip you with both basic techniques and creative ways to capture the night sky.
As a hobby, astrophotography requires two types of investment. The first is financial: you’ll need a camera, at least one lens, and a few accessories, as well as a warm coat for cold nights spent under the stars. Take a look at our guide to the best cameras for astrophotography and best lenses for astro to help get you started with this aspect of astrophotography.
The second investment is time and patience — though these are things you sadly cannot purchase. Astrophotography is a photographic style that’s tricky to get right the first time and will take many attempts, iterating on the same ideas until you can finally provide an image that’s got some real ‘wow’ factor.
In this guide, we’ll cover everything you need to get started — the equipment you’ll need, as well as planning your astro shoot and the camera settings you’ll need to effectively photograph the night sky. We also include some tips on getting the most out of the images you capture, including editing them in some of the best photo editing apps available.
The first bit of advice, though, is a simple one: have a go. Even if you don’t own a flashy camera, use what you have. You can even use your smartphone for astrophotography if necessary. You’ll be surprised what they’re capable of, particularly using the night modes on more recent models. Thinking of dabbling in astrophotography?

Astrophotography for beginners 2023
Camera bodies and lenses
If you’re using a DSLR or mirrorless camera, the first step is to put it in Manual mode — this applies to both exposure and focus. We always recommend using manual focusing when shooting astro, as most sensors simply won’t be able to focus on the night sky because it’s so dark. Use the screen on the back of the camera (having one that flips out makes this easier) to focus carefully so the stars appear as points and not circles. Stopping the lens at infinity isn’t enough, so zoom in if you can using the screen’s controls to get your focus as accurate as possible.
Full frame cameras generally perform the best in low light situations as they have a larger sensor and can have larger individual photosites that capture more light. However, as megapixel counts increase (and photosites, therefore, become smaller) this advantage is becoming slimmer, and modern crop-sensor cameras are very capable for astrophotography. They are also a more affordable option than full-frame cameras.
As a rough guide, a good full-frame mirrorless or DSLR with the ability to take sharp images at higher ISO settings will set you back between $2000-3000 — more on that later. Crop-sensor or APS-C cameras are usually $400 and up, and are more than capable of capturing the night sky.
When it comes to lenses, a wide or super-wide angle ‘fast’ lens somewhere in the 12-35mm range is best suited to landscape photography and astrophotography. Wide-angle focal lengths allow you to capture a good portion of the night sky as well as some of the landscape for foreground interest. A ‘fast’ lens is one that has a large maximum aperture — in other words, a small f-stop number. A lens with a maximum aperture of f/2.8 or lower is considered to be a fast lens, though many astrophotographers opt for prime lenses with apertures of f/1.8 or lower as they tend to be sharper and better for astrophotography.
A lens like the Rokinon (Samyang) 14mm f/2.8 is a great lens to get started with and is very affordable. If you’re ready to spend a little more, the Sigma f/1.4 14mm ART or the Sony FE 14mm f/1.8 GM lens would both be great options. If you don’t have a fast lens just yet, you can still use the kit lens that came with your camera, even if it’s just to practice with to get your technique and settings right. Just make sure you operate at the maximum available aperture size (typically around f/4 on stock kit lenses).
When it comes to accessories, a tripod is essential for astrophotography as you simply won’t be able to hold the camera still enough by yourself for the long exposures required, and resting it on a wall isn’t always possible. The tripod’s smoothly tilting head also allows you to position your camera perfectly to capture the bit of the sky you want. We have a guide to the best tripods for night sky photos if you’re in the market for one.
Additional equipment for astro
Remote Shutter Release (recommended)
This is a button on a cable that will allow you to trigger your shutter to minimize the risk of introducing vibrations in the camera. You just plug it into the appropriate port in your camera, and press the button on the cable instead of the button on the camera. These are very inexpensive, although, you can get wireless ones that cost a little more. If you don’t have a remote shutter release, you can instead use the timer delay on your camera to ensure there is no movement of the camera when taking a shot. Some DSLRs have a mirror lockup function that prevents the movement of the mirror inside the camera body from inducing vibrations, but this isn’t necessary for mirrorless cameras.
Intervalometer (optional)
If you’re shooting star trails and need to take sequences of shots, then an intervalometer of some kind is an essential accessory. However, this is quite an advanced form of astrophotography, so we wouldn’t necessarily suggest you head out to get one right away if you’re more of a beginner. When you feel you’re ready for star trails, we have a guide on how to photograph star trails and the best intervalometers which you may find useful. Many modern cameras have interval shooting built-in, so spend some time with your camera’s manual to figure out how it works.
Headlamp
Keep your hands free to operate your camera by using a headlamp at night and, if possible, use the red light mode (if it has one) to preserve your night vision. A headlamp is also helpful for ‘light painting’ objects in the foreground of your images — either creatively or just to improve the exposure. Alternatively, a flashlight with a bit of red plastic over the end can achieve the same thing.
Finally, if you’re going to be shooting in cold temperatures, it might be worth investing in some kind of lens heater. These can prevent condensation from creeping into your lens and ruining your shot.
Planning your astro shoot
Location
Light pollution is a serious problem that astrophotographers often have to overcome. You’ll need to be in a dark sky area to be able to capture really detailed images of the night sky, so make sure you head away from urban areas and street lights. There are some really useful websites such as Dark Site Finder and Light Pollution Map that will help you to find a suitable location to shoot. You’ll also want to get weather reports and guidance on where to point your camera when you shoot. The best stargazing apps only cost a few dollars/pounds, and they’re extremely helpful when it comes to selecting your location and knowing the best time to shoot.
Subject
The night sky changes constantly throughout the year, and knowing what you are likely to see and be able to photograph in the sky is a key component of astrophotography. There are some excellent apps like Stellarium and Starwalk 2 which allow you to visualize how the night sky will look at any time and date for a specific location. But remember, things like meteor showers and comets are unpredictable, and the weather can easily close in and spoil everything — remember when we said you’ll need patience?
Astrophotography settings for your camera
There are no one-size-fits-all settings that will give you a perfect exposure for every situation. Sadly, photography just doesn’t work like that. However, there are a handful of basic rules you can follow to maximize your chances of nailing that astro shot.
Camera Shooting Mode
Put the camera into M, or Manual mode using the mode dial on the top of the camera. This will give you the ability to alter the shutter speed, aperture, and ISO manually rather than having the camera do it for you. Never shot in manual before? Don’t worry, read on to find out what you need to do.
Aperture
You want your aperture as wide as possible in almost all astro situations, so set it to an f-number of f/4 or lower. We usually recommend f/2.8 or lower but use the maximum your lens is capable of. Many DSLRs and mirrorless cameras use a wheel on the camera body to set the aperture, but manual lenses and some made for Sony mirrorless cameras have an aperture ring on the lens itself.
Lower F numbers always mean wider apertures and greater light-gathering ability — this is why prime lenses with apertures of f/1.8 and lower are generally favored for astrophotography.
Image File Type
Set your camera to record RAW image files. Astrophotography can be broadly split into two separate areas — photography and post-processing. In order to process your newly acquired astro images back at home, you will need to shoot in RAW so that you capture and retain as much data as possible. A RAW file is the information from the camera’s sensor with no processing applied.
Recording JPEG images will give you smaller files, but the compression process throws away important data you could use. If necessary, buy a larger memory card that can handle RAW files rather than shoot JPEG.
Shutter Speed
The aim of astrophotography is to capture as much light as you can while minimizing the movement of the stars in the image — unless you’re deliberately trying to create star trails. The longer the focal length of your lens, the shorter the shutter speed will need to be in order to avoid capturing star trails.
There’s a simple formula to calculate the correct shutter speed for any given lens, called the ‘500-rule’. In its simplest form, this is 500 divided by the focal length of your lens. For example, if you are using a 20mm lens, this would be 500 / 20mm = 25 seconds. This, however, only applies to full-frame cameras. For a crop sensor camera, the crop factor needs to be taken into account, so in this instance, we would recommend using a base value of 300 for APS-C cameras, and 250 for Micro Four Thirds cameras.
Start with an exposure of 20 seconds, which is about the longest you can leave the shutter open before stars begin to trail and see how that looks. You can then adjust as needed.
ISO sensitivity
The higher the ISO, the more amplified the light signal captured by your camera’s sensor will be. You will need to shoot at a high ISO for astrophotography, but there’s a trade-off — the higher the ISO, the more noise (a type of digital degradation) you will begin to see in the image, and every camera increases noise in a different way. Some slowly ramp it up, others make a big jump after a particular setting — check out our guide to the best cameras for low light photography to see which ones do this better than others.
Focusing in the dark
First, set your lens to manual focus using the AF/MF switch on the lens — autofocus will not work in the dark. Then use the ‘Live View’ feature of your camera to display an image preview on the camera’s LCD screen. Identify a bright star or distant light source and digitally zoom in on that point of light. Once you’ve done this, adjust the focus ring until the star or distant light source becomes as small and sharp as possible.
Once you’re focus is set, now all you have to do is take the shot and wait for the image to pop up on the LCD display — it may take some time before you see the image on the LCD screen, as the camera can take a while to write the file to the memory card. If your foreground is looking a bit dark, try light painting your subject with a flashlight or your smartphone light during the exposure to help brighten the scene. You may need to adjust the ISO or aperture slightly to find what works best for your location, but you are now firmly on your way to capturing your own images of the beautiful night sky.
Tips and advice
Foreground
If you’re trying to balance the light and focus between the foreground and the night sky, we suggest you take multiple exposures of each element and merge the images together when you edit them, as they will require different settings to get the best of each. You may even find that getting your foreground shots an hour or so earlier during blue hour will help, as there is more light to work with for your foreground objects without having to crank the ISO up. This isn’t always possible, though.
Reflections
If you’re shooting the night sky near a lake, and the weather is still, there’s a great opportunity to try capturing the reflection of the stars in the water. There are several ways to do this, depending on the conditions. We prefer to do the hard work during the shoot, so would suggest changing your focal point to the water and taking an exposure, then setting your focus back to the night sky and taking the exact same shot — you can merge them later in the edit.
You may find you need to balance your shutter speed a little here, depending on the conditions — a 20-second exposure will capture the reflection of the stars, but you may pick up movement on the water that reduces the clarity. You could try shorter exposures for your reflection shot but may have to work harder to bring out the stars in the edit. Lightroom’s linear-gradient edits are perfect for bringing out the clarity and sharpness of reflections, so give that a go.
White balance
While we’d usually recommend setting your white balance to a slightly cooler temperature for astro shots, you can experiment with either the manual WB settings or the presets, to create interesting tints and variations to your shots.
If you’re getting a little light pollution, adjusting the white balance can actually make it look like a feature of the photo (we recommend cooling it right down and seeing the effect that has), although you’d need a gradient filter to reduce noise if you’re closer to an urban area. Though to start out with, you can just use the ‘Auto White Balance’ setting and experiment with cooler and warmer adjustments when you edit to see which effect you prefer.
Skywatchers across the world were treated to rare dancing light displays on Sunday and early Monday as the northern lights stretched much farther south than usual. With the colors dazzling viewers as far as Texas, this may have been the most widespread aurora borealis since 2003, report Matthew Cappucci and Kasha Patel for the Washington Post.
“The show lasted about 20 minutes all together, and [then] burst in intensity for about five minutes, with these beams of white light coming down from the sky,” Eric Eisner, a high school teacher from Santa Monica who viewed the aurora while camping in the Owens Peak Wilderness in California, tells Amy Graff of SFGATE. “It’s the kind of thing where you wake up in the morning and you’re like, ‘Oh that must have been a dream,’ but you realize it was real.”
Auroras occur when charged particles from the sun collide with gases in our atmosphere. The aurora borealis (also called the northern lights) and the aurora australis (southern lights) commonly occur close to the poles, because the Earth’s magnetic field steers the charged particles there.
But every so often, the sun spews out large amounts of plasma, charged particles and magnetic energy called coronal mass ejections (CME) that hurtle toward Earth as fast as 6.7 million miles per hour. This material can spark a geomagnetic storm, or a disruption in the magnetic field surrounding Earth—and experts say strong ones are growing more common. The storm that hit on Sunday was rated “severe,” a 4 out of 5 on NOAA’s scale, causing the auroras to be larger than usual.
“The way this storm—this CME—connected was just perfectly connected to Earth’s magnetic field,” Bill Murtagh, program coordinator for the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center, tells the Post. “Consequently, the storming was up at the severe level versus just the moderate, maybe strong, level that we might have expected.”
During this week’s storm, the northern lights stretched as far south as Colorado, New Mexico, France and Germany, while the southern lights appeared as far north as the Central West region of Australia’s New South Wales, reports Daisy Dobrijevic for Space.com. Viewers reported spectacular colors ranging from reds to greens and yellows—a variation caused by atoms of different elements reacting with the solar energy at different altitudes.
Storms like this one are expected to get more common in the near future. The sun’s activity level fluctuates over an 11-year cycle, and during that period, severe geomagnetic storms typically occur about 100 times. The surges in energy from these storms can cause disturbances in the power grid, GPS and radio communications, in addition to creating fantastic displays in the sky. Our current solar cycle is expected to peak in July 2025, which means we can expect increased activity of this kind over the next few years.
“We’re in a ramped-up, elevated stage from now for the next four, five, six years,” Murtagh tells Grace Toohey of the Los Angeles Times. “We’ll certainly see more [auroras]. … If you missed this one, stay tuned, there’s more to come.”
“One night I set up a field scope on the grill. I was amazed by the detail I saw on the moon. I said to myself that I’m buying a telescope tomorrow.”
Now, approaching five years later, Titus has built his own observatory, runs his Facebook page, and has become vice president of the Cincinnati Astronomical Society.
The mostly-wooden observatory consists of two floors: a lower level containing a computer workstation where Titus refines his images, and an upper level where a human-sized telescope lives. Titus has installed metal retractable panels that open when he wants to view the sky, and can rotate the second floor to face any direction he pleases. Titus did not give an exact figure for how much he spent building the observatory, but implied it was well into the thousands.
The Cincinnati Astronomical Society (CAS) has a history stretching back over a century and is one of the oldest organizations of its kind in the nation, according to president Bryan Simpson.
Founder DeLisle Stewart created CAS in 1911 as an astrophotography-focused group after the Cincinnati Observatory refused to provide him necessary photography equipment. Now, the volunteer-only organization serves as a gathering place for local astronomers and an educational body that frequently does outreach events.
The society has headquarters in Miamitown, where it holds its members-only meetings, and also has two other properties in rural Adams County, Ohio and Bracken County, Kentucky that are set up for camping and stargazing.
“To do astrophotography, you have to have a dark sky,” Simpson said.
Simpson also recognized the contributions of Titus as a newer yet extremely devoted member.
“He’s already in the top three or four astrophotographers in the area,” Simpson said. “He has a real passion for it, and I hope that spreads to others.”
Ryan Martin, another CAS member and astrophotographer, is one person who Titus has already spread his influence to.
“Mike has inspired me to do an observatory,” Martin said. “I have the two telescopes I want and am really excited about this coming summer.”
Martin has been a member of the astronomical society since December 2019, after he “fell into a YouTube rabbit hole of astrophotography” while dealing with a foot injury and decided to take up the hobby using a telescope he had been given as a child.
Neither Martin nor Titus have an academic background in astronomy. Titus said he largely educated himself on the subject through Wikipedia articles, library books, and instruction from fellow CAS members.
“You can’t discount the contributions of amateur astronomers to the field,” Simpson said.
It’s possible that Titus has already made major contributions to the field, as he has sent images of multiple asteroids to the Minor Planet Center for review as potential new discoveries.
While he waits for word back, Titus will continue to operate his observatory each night, searching for the next big photo op and hoping no clouds or rogue satellites will get in the way.

The AlUla Skies Festival is returning for a second year, from April 26th until May 13th, with a range of adventure, cultural, heritage, and entertainment experiences.
Read More: Here is a List of Top Events to Attend in Saudi Arabia 2023
A host of unique activities, including hot air balloons and stargazing, are sure to provide an incredible spectacle from every angle.
Visitors will have the chance to view AlUla from a hot air balloon or helicopter during the daytime, while stargazing, music shows, and astrophotography will be among the nighttime activities.
Phillip Jones, chief tourism officer at Royal Commission for AlUla (RCU), said: “AlUla Skies Festival is a unique opportunity to welcome visitors from the Kingdom and the world to AlUla, to further strengthen its position as a leading tourist destination in the region.
“Since ancient times, the sky has been a map for those who visited AlUla, as they were guided by the stars and the constellations to travel on the ancient incense trading route, and today we celebrate the history of the skies with unique events and offers that position AlUla Skies Festival as a must-do on the travelers bucket list every year.”
Hot air balloon trips in North Hegra will operate each day from 7 am to 8:30 am and 4 pm to 5:30 pm. You can book your flight over the UNESCO World Heritage Site here.
Helicopter tours will give you birds-eye views of AlUla’s most famous landmarks and heritage sites. The flight duration is 30 minutes.
Meanwhile, AlUla Skies is also providing a combined experience of stargazing and astrophotography from 4.30-10.30 pm daily, in an area that offers some of the very best views of the night sky.
A Giant Swing where participants jump off the mountain edge and swing is also available, an outdoor cinema, and AlUla Stairway, with a descent all the way back down on a 150-meter zipline, are also available during the event.
One of the our top-rated astrophotography cameras is massively reduced at Walmart.
The Olympus OM-D E-M1 Mark II is one of the best astrophotography cameras that money can buy right now – but it doesn’t come cheap. That’s why we were so surprised to stumble upon this doozy of an offer from Walmart.
The retailer is offering the OLYMPUS OM-D E-M1 Mark III for just $1204.95 – a discount of nearly $600 from the MSRP of $1799. Weirdly, the Walmart page doesn’t mark it down as a deal, but this is indeed a great discount on this lightweight astro camera.
Update: The price jumped up by about $60 since we first published about it, so we’ve updated the article accordingly. It was $1141.97, it’s now $1204.95 – still a great deal.

Save nearly $600 on one of the best astrophotography cameras around (lens not included)View Deal
One of the best features of the OLYMPUS OM-D E-M1 Mark III is its Starry Sky Autofocus, which means the camera is able to use an algorithm to zero in on the smallest stars visible for an impressively sharp picture.
There are two priority modes, too; one for accuracy, and one for speed. The former is ideal for tripods, but the latter means you can grab some great astrophotography shots with a handheld camera. Don’t worry about your arm getting tired, either – the OLYMPUS OM-D E-M1 Mark III is impressively compact and lightweight.
That small size does mean the sensor is a little smaller, but with the wealth of features on offer we’d say it’s still worth a look.
There’s even a Live Composite mode that keeps the shutter open for six hours, adding exposure when lighting changes, and USB connectivity is ideal for keeping the battery topped up while out and about.
You will need your own lenses, however, as this deal is for the camera body only.

La noche del pasado 23 de abril una gran eyección de masa coronal producida por una tormenta solar de clase G4 (KP8/9) alcanzó el campo magnético terrestre a 580km/s. El efecto de este repentino impacto energético se ha traducido en vistosas auroras boreales de colores verdosos y rojizos en zonas próximas al circulo polar como es habitual pero no es tan frecuente que estas auroras se dejen ver en latitudes más bajas como Francia e incluso España como muestran las cámaras del observatorio de Calar Alto.
Obviamente el espectáculo no se ve igual desde nuestras latitudes que desde las zonas árticas. Aquí se pudo apreciar solamente como una tonalidad rojiza hacia el horizonte norte, difícilmente visible al ojo humano excepto si nos encontramos en un lugar sin contaminación lumínica, pero las cámaras fotográficas en modo de larga exposición si son capaces de captar esa tenue luz.
Las auroras son fenómenos nada inusuales que tienen ciclos de actividad motivadas por nuestro Sol. Actualmente nos estamos acercando al máximo solar del ciclo 25 por lo que es buen momento para plantearse un viaje a observarlas. La noticia no obstante radica en el hecho de poder apreciarse en esta ocasión desde latitudes tan bajas como las de España (hay algunos registros que hablan de auroras visibles en nuestro país durante la Guerra Civil). De hecho las auroras han llegado a ser divisadas desde latitudes de 29,5ºN en la frontera entre Estados Unidos y México.
Las redes sociales se han llenado de imágenes de personas que han capturado el fenómeno incluso con sus teléfonos móviles. Habrá que estar atento a las próximas tormentas solares y tener nuestras cámaras de fotos preparadas.

Boasting the build quality we’ve come to expect from the other models in Celestron’s NexStar range, the 4SE is optically comparable with the aforementioned Celestron Astro-Fi 102 but instead of relying on a smartphone, this model comes with a chunky and tactile hand controller. It is a good buy for beginner astronomers as it’s very simple to use and produces a clear and bright picture which is why we gave it four out of five stars during our Celestron NexStar 4SE telescope review.
The field of view is somewhat limited, which some users may find frustrating when manually slewing, but as Celestron’s SkyAlign software and GoTo system finds objects for you, this isn’t a deal breaker. The hand controller also allows nine different slewing speeds allowing for small corrections or a quicker scan of the night sky if you choose.
Given the power-hungry nature of the NexStar SE scopes, an external power supply is advised. The scope can otherwise quickly drain a whole pack of AA batteries. This does further limit portability further unless you are using it in combination with a portable power station (opens in new tab).

An excellent telescope for the beginner or those on a tighter budget, the Celestron Inspire 100AZ is a great choice for those looking for a complete package that offers more in the way of accessories than most starter telescope bundles.
The Inspire 100AZ comes with a 90-degree erect image diagonal with a 1.25-inch fitting that makes the telescope suitable for terrestrial (daytime/on land) and celestial views, a pair of eyepieces (20 mm and 10 mm), a red LED flashlight for preserving vision, an accessory tray, StarPointer Pro finderscope and a smartphone adapter for basic astrophotography. Be mindful that given the refractor’s focal ratio, the Inspire 100AZ is limited to short-exposure photography.
During the observations we made in our Celestron Inspire 100AZ review, we noticed a small amount of false color (purple color fringing), and a slight blurring in the field of view was noticeable. The latter is easily resolved with a careful selection of eyepieces, so we recommend investing in one of the best eyepieces to make the most of the Inspire 100AZ’s optical system and to ensure that it translates into the quality of your photos, if you’re taking them False color, on the other hand, is to be expected in telescopes at this price point but it doesn’t ruin the experience unless you’re exceptionally particular about color accuracy.
The overall build of this refractor is impressive. The StarPointer is a pleasant surprise since it’s able to pick out faint stars under moderate light pollution for an accurate star-hopping experience.

After undertaking our Celestron Astro Fi 102 telescope review we’d say this is perfect for beginners who don’t have prior knowledge of the night sky but want to start learning and enjoying it straight out of the box.
It’s not a budget scope by any means, but if you’re looking for a telescope that comes from a trusted brand that is highly portable, this one is worth your consideration.
This is an excellent grab-and-go option when weighing in at just 6 lbs (2.7 kg). It doesn’t have a huge footprint as some telescopes do, so you can leave it set up at home without compromising your space too much, though it is easy enough to pack away and reassemble at will.
We think the final finish on the telescope looks and feels a little toyish, and compromises such as the materials used have been made to keep the scope as lightweight as possible. Despite the slightly lackluster final finish though, the image is attractive, and you can explore the detail on the Moon’s surface, Saturn and its rings, Mars and Jupiter. You may also see nebulas and other deep sky objects in the right sky conditions. It’s swift and easy to sync with Celestron’s SkyPortal app, which contains approximately 100k celestial objects to explore.

The optical system of the Celestron NexStar Evolution 9.25 (opens in new tab) ranks as one of the best we’ve ever had the pleasure of observing the night sky through. With no interference or optical defects in the field of view, this high-quality instrument offers sights of a wide selection of astronomical targets with impressive clarity and contrast.
Although it is expensive (sitting around $2850), you get a lot of value for money with this telescope and its setup. The list of accessories you get include an attachable camera, a red dot finderscope, an international AC adapter, hand control for a seamless AutoAlign process and 13mm and 40mm eyepieces.
The stand-out piece of equipment with the NexStar Evolution 9.25 is undoubtedly its single-fork arm. Observers can slew from one target to the next and continue onwards at the touch of a button for up to 10 hours of continuous use, thanks to its rechargeable lithium-ion battery.
Built into the mount is the telescope’s very own Wi-Fi network, allowing the instrument to connect and control via the Celestron SkyPortal app (downloadable for free on iOS (opens in new tab) and Android). Being motorized, the mount can track objects as they move across the sky, making the NexStar Evolution 9.25 a must-try for astrophotography.
If you have the budget and if you’re looking for a complete high-definition tour of the universe, then we fully recommend this GoTo to seasoned skywatchers. The only downside is that the NexStar Evolution 9.25 is tricky to transport due to its weight, meaning that skywatchers will need to consider this before planning any trips beyond the backyard — a small trade-off given the telescope’s robust and high-quality design.

When we reviewed the Celestron Astro Fi 130 telescope we liked it a lot and think it’s excellent value for money. While it’s not necessarily a budget telescope, it is a lot more affordable than a few of the other telescopes in this guide, we think it’s excellent value for money.
If you’re new to stargazing, or even if you just don’t have a lot of experience, this telescope can give you an astronomy experience to marvel at using telescope technology and good optics, serving as a virtual guide to the night sky.
A 130mm aperture means that plenty of light is able to travel through the lens, making the night sky targets clearly visible and giving you amazing views of stars. A focal length of 650mm means you’ll get a wide field of view (you can see a lot at once).
This telescope is also sturdy but still lighter than some other scopes you might consider for the same experience, so it scores well on ease of transport. You also get a stable tripod, a red dot finder and eyepieces, which makes this even better value for money.
We can only think of two things that let you down a bit with this model: the battery life drains a little quicker than you might want, and the eyepieces aren’t the best. We think you should consider upgrading the eyepieces for a better experience, but for value for money, we highly recommend this scope.

The first of three of the NexStar telescopes on this list, and for a good reason. The Celestron NexStar 8SE is an excellent option for beginners and seasoned skywatchers. This telescope makes it easy for novices to view the night sky without knowing much about astronomy. At the same time, more experienced stargazers can use it to explore deeper into space or even attach a camera for impressive astrophotography.
If you pay a good chunk of money for a telescope, you can expect to receive exceptional optics with extraordinary views of a wide range of celestial objects.
The NexStar 8SE by Celestron is renowned and has earned the title ‘The World’s most beloved telescope.’ It is the number one bestseller on B&H Photo (opens in new tab). Featuring StarBright XLT optical coating, this telescope provides unparalleled clarity and contrast for viewing planets and the moon. Jupiter, its moons, Saturn, and its rings are breathtakingly vivid with no chromatic aberration or color fringing. Its 203.2 mm aperture lens allows for excellent views of deep-sky objects.
In our Celestron NexStar 8SE review, we walked you through what it’s like to get everything set up, and it’s very straightforward. No prior knowledge of the night sky is needed, as you can use Celestron’s SkyPortal app or any other stargazing app to help you find two stars for the alignment process.
Once the telescope is aligned, you can use the solid-in-the-hand, hand-held controller to direct it to any item in its massive database. This includes planets, galaxies, double stars, star clusters, and nebulae. A fantastic option for beginners and indecisive people is the ‘sky tour,’ which automatically directs the telescope to different interesting cosmic objects.
The motor runs smoothly, and the results are precise. Automatic tracking is a dream for astrophotographers, enabling them to take long exposures, which can then be stacked post-shoot to create beautiful images.
The Celestron NexStar 8SE comes with a hefty price tag, but it is well worth the investment for those serious about skywatching or astrophotography. Although it may be too pricey for those who are only casually interested in the solar system, it is an excellent choice for those who plan to engage in these activities for the long term.

Needs extra support in windy conditions
As an introduction to the world of GoTo skywatching, the Sky-Watcher Skymax 127 SynScan AZ (opens in new tab) is a must-have for observers on a tighter budget. The SynScan AZ hand controller offers information on over 40,000 astronomical objects, which includes the most complete catalogs (Messier, NGC, IC and SAO) of deep-sky and solar system targets.
The astronomer has everything they need for a successful night under the stars: good quality star diagonal, 2x Barlow with a camera adaptor, 6×30 finderscope, a stainless steel tripod and an accessory tray.
Assembling the instrument is easy and, given the weight of 39.7 lbs. (18 kg), the Sky-Watcher Skymax 127 SynScan AZ is light enough to carry across the backyard without a great deal of effort. Skywatchers have the choice of powering the Servo Drive with 8 AA batteries or a 12V power supply — because batteries tend to drain quickly in when it’s cold, we recommend investing in the latter for uninterrupted observations with the SynScan technology.
Alignment is simple, using two stars to set the instrument up, but beginners may need practice in getting this just right — we recommend becoming acquainted with the Skymax 127 before dark, ensuring that you read the manual from cover to cover.
In terms of optical prowess, we don’t have any complaints. We can fit a waxing gibbous moon phase in the field of view and, after tweaking the focuser, the craters and lunar mare come into exquisite focus, with lovely contrast and clarity. A moon filter offered even better sights. Slewing over to the star-forming region, the Orion Nebula (Messier 42), is also picked out easily with the 5-inch (127 mm) aperture — it appears as a dusty patch of light with the Trapezium Cluster’s member stars dazzling with brilliant clarity at the nebula’s heart.
The stainless steel tripod can be a bit unstable, so we suggest supporting the setup while slewing in windy conditions.

Celestron’s range of NexStar telescopes has a well-deserved reputation for excellent optics, user-friendly assembly and a plethora of features. The telescope exemplifies all of these which we outlined in our Celestron NexStar 6SE review.
If you’re looking for a telescope with great light-gathering capabilities and a vast selection of astronomical objects to explore, this is an excellent choice. The 5.91-inch (150 mm) aperture provides superior performance compared to the Meade StarNavigator NG 114, while the NexStar+ hand controller contains an expansive database with over 40,000 objects. Unfortunately, extra eyepieces will need to be purchased in order to get the most out of the telescope, and even then, not all objects listed in the database can be viewed in great detail.
The NextStar 6SE offers a great way to explore the night sky using its ‘tour mode’. It will guide you through different targets across the sky, or in specific constellations, so you can observe like never before. This is perfect for those who don’t know what to look for or just want to get straight to observing interesting celestial objects that have been chosen for them.
The SkyAlign technology is simple to use and gets you pointed in the right direction fast. The motorized mount also has nine slewing speeds on top of its different tracking rates. All of this sounds brilliant, and it is, but there is a downside. The NexStar 6SE’s battery can drain very quickly, so we recommend powering the setup with an external power source.
Astrophotographers may initially be displeased with its slow f/10 focal ratio, limiting the NexStar 6SE to being a planetary or lunar imager at best. Still, there is the facility for more advanced users to switch out the secondary mirror for their camera, increasing the focal ratio to an astrophotography-friendly f/2.

The Unistellar eQuinox 2 is the latest smart telescope to be released by Unistellar and proceeds to take over from the previous model the Unistellar eQuinox. In our Unistellar eQuinox 2 review we tested it for ease of use, robustness and compatibility with smart devices and found the smart telescope to be eminently usable, not least because of its Smart Light Pollution Reduction feature which aids its use in urban environments likes towns and cities.
A simple design with a single button on the telescope itself and a slotting mechanism with just two screws to hold it aloft the sturdy tripod makes this telescope one of the simplest we’ve ever reviewed (alongside the Unistellar eVscope 2 we reviewed). Users will take only a few minutes to get it out of the box and ready to synchronize with the smart device app (available on iOS and Android) and after a quick pairing we could manually slew the telescope and enhance exposure settings.
When the telescope is oriented, which it does by automatically orienting using the night sky and its on-board image sensor, the app allows us to automatically go-to night sky objects like galaxies, star clusters, nebulas and planets without any required knowledge of the night sky or constellations.
Best for tech fans — smart views of the night sky for beginners and veterans alike
At $2499 (opens in new tab)/£1982, the Vaonis Vespera is the smallest and most reasonably priced smart telescope to date. This telescope from French startup Vaonis is a smaller, lighter version of its robotic older sister, the Stellina.
Named after the Latin word for ‘evening,’ Vespera does not have an eyepiece like traditional telescopes but instead captures and shares images of the night sky with up to five connected smartphones or tablets through a mobile app called Singularity (opens in new tab).
The Vespera is effectively a camera for taking stunning pictures of deep sky objects, even in light-polluted cities. It is not intended for observing the moon and planets, but it can be used to capture remarkable images of star clusters, nebulae, and galaxies. Here is all the information you need to know about how the Vespera works.
The Vespera is an impressive device that combines three technologies: star pattern recognition software, image live stacking technology, and an app. When switched on, its Sony IMX462 image sensor can detect a target in five minutes and take one photograph every 10 seconds (this varies depending on the target). This noise-canceling process can be seen in real-time on the Singularity app, resulting in a clearer, more contrasty and colorful image. In our Vaonis Vespera review we found that the images were a little soft, but they could be enhanced with post-processing.
Additionally, it uses a planetarium to generate a ‘tonight’s best’ list of celestial targets and an algorithm to determine the camera settings for viewing each target.

The eVscope 2, a telescope designed with great finesse, is ideal for photographers who are new to astronomy and have a considerable amount of money (about $5000 (opens in new tab)) to spare or for astronomers who desire an all-in-one system that is effortless to set up and use. Even though it may not be greatly appreciated by experienced telescope users accustomed to a more traditional viewing method, it can still create remarkable images.
The Unistellar eVscope 2 is a step away from traditional telescope stargazing and instead hosts an in-built camera, sleek design and electronic eyepiece. It is the second iteration of the eVscope line and has some noticeable improvements in both design and accessibility. It features a 4.5-inch (114mm) reflector with a focal ratio of f/3.9, which makes it ideal for viewing celestial objects such as nebulae.
Inside is a 7.7MP image sensor and new to the eVscope 2 is an electronic eyepiece designed by Nikon for those that want to get tactile with the telescope. The simple layout, stylish design, and excellent smartphone app user interface makes the eVscope 2 a doddle to use and photograph the night sky with, especially with its enhanced tracking feature, which we were very impressed with in our Unistellar eVscope 2 review.
Due to the high cost of all the premium features, in reality, it is reserved for those with a substantial budget.

Sitting at a price of less than $300, the Sky-Watcher Explorer 130 EQ2 is an excellent choice for those serious about taking the first steps into the world of astronomy.
Unlike other models at a similar price point, this telescope ships with an equatorial mount. When it is aligned with the Earth’s axis, it makes it simple (after some practice) to track objects in the sky once you’ve found them, as the Earth rotates.
It has a good-sized aperture at 5.1 inches, which means, unlike the models above, you will be able to explore deep sky objects, albeit only the brightest ones.
While not as long as the Celestron Inspire 100AZ, the Sky-Watcher Explorer 130 EQ2’s long tube length results in f/7 and makes high magnification possible. During our review of the Sky-Watcher Explorer 130 EQ2, using the supplied Barlow lens, we could easily get sharp views of the Jovian System (Jupiter, its rings and moons) and Saturn’s rings looked impressive.
This telescope is best suited for backyard stargazing, mainly due to its 12.6kg combined weight, which makes it a little more of an ordeal to take it out and about on sky-watching trips.

The Orion Skyline 6″ (opens in new tab) telescope is a great choice for beginner and intermediate astronomers alike due to its easy-to-use nature and high-quality optics.
This telescope offers an impressive 152mm objective lens, allowing for plenty of light to pass through and making night sky targets more visible. The multi-coated optics further enhance the viewing experience, ensuring a clear image of those targets. With a focal length of 1200mm, you can observe the finer details of celestial bodies, such as craters on the moon and features of other planets.
This powerful telescope offers up to 133x magnification, allowing you to observe celestial objects in incredible detail. With the included eyepieces, this level of magnification is perfect for viewing the moon and planets. You won’t miss out on any of the finer details.
It’s also well built and easy to use, a huge plus for those without bags of astronomy experience. However, you can get alternatives for a lower price, even if they don’t quite match the Skyline 6″ for quality of specs. We also like the Orion AstroView 90 (opens in new tab) a lot, for which this is a suitable replacement, however, it’s hard to find it in stock online.

Lens cap can be fiddly
Celestron’s EdgeHD technology turns Schmidt-Cassegrain telescopes into high-quality astrographs with perfectly flat fields. The way that the Schmidt-Cassegrain optics focus light usually means that the focal plane — where the light comes to focus — is curved, but if you are imaging, your CCD camera’s sensor is flat. A curved focal plane on a flat CCD sensor results in field curvature, where stars at the edge of the field tend to blur. This is generally an unwanted effect for astrophotographers.
We were pleased to find, during our Celestron Advanced VX 8 EdgeHD review, that the optics in the EdgeHD negate the blurred edges, creating a perfectly flat field right to the edge of the frame for pinpoint sharpness across the whole image. The optical performance that the Celestron Advanced VX 8 EdgeHD delivers is impressive, with crisp and clear views with no optical distortion or false color.
As an added bonus, the optical tube assembly comes packaged with Celestron’s Advanced VX mount, which is tailor-made for imagers, capable of photographing across the meridian (an imaginary north-south line) without needing to do a meridian flip. The setup also performs periodic corrections to remove errors when tracking objects and also features an auto guider port.
The Celestron Advanced VX9.25 EdgeHD can carry a load up to 30 lbs. (13.6 kilograms) too, so the tube and all your imaging accessories are fully supported and stable. Also included are the standard NexStar+ hand controller, a 40 mm eyepiece, and access to Celestron’s SkyPortal app (opens in new tab) and Starry Night Special Edition software (opens in new tab).

For versatility in the type of mount you choose, a Vixen-style dovetail plate is supplied for a moderate price tag.
The Skymax 150’s optical prowess is outstanding, with no sign of optical distortion. The telescope is a great all-arounder, suitable for imaging everything from the planets to deep-sky galaxies and nebulas — and as you would expect for a telescope designed for giving great images. As an added bonus, the instrument is a breeze to use and accessorize.
The focuser is lovely and smooth to operate and the Skymax 150 keeps a good amount of fine focus once it’s been found — vital for those long imaging sessions.
Telescope FAQ
Telescope types compared
If your biggest question is, ‘which type of telescope type should I buy?’ or ‘what is the best telescope in the world?’ let us help. There are three types of telescopes: Reflector vs refractor vs catadioptric telescopes. There are some key differences between how they work and how each type of telescope is helpful for different observations. Telescopes look visually similar from when the telescope was invented but there have been many improvements to both design and function over the years.
Before purchasing one of the best telescopes available, it is important to consider your desired outcome. Are you looking to observe distant star clusters, nebulas and galaxies? A reflector telescope is undoubtedly the most suitable option if the answer is yes.
Telescope Glossary
Aperture: The diameter of the primary mirror or lens, where the telescope collects light. Field of view: Area of sky visible through the eyepiece. Focal length: A telescope’s tube length. Short focal lengths offer a wide field of view and a small image. Focal ratio: Also known as the telescope’s speed. Small focal ratios provide lower magnifications, a wide field of view and a brighter image. Magnification: The relationship between the telescope’s optical system and the eyepiece.
Alternatively, a refractor telescope is the best choice if you are mainly interested in seeing the moon and other planets in our own galaxy.
Another option would be a catadioptric telescope, which can work as a happy middle ground. Some models have computerized motors that make aligning and tracking targets easy and can even capture images for you, excellent news for astrophotographers.
The aperture size is one of the most important things to consider when purchasing a telescope, followed by the focal length. The main thing to remember here is that bigger isn’t always better.
It all comes down to what subjects you want to view. Shorter focal lengths, saf about 20 inches (500 mm), will provide a field of view for you to take in large areas of the Milky Way and showpieces such as the Pleiades (Messier 45) and Orion Nebula (Messier 42). Meanwhile, high-power objects like the moon, planets or double stars need a telescope with a longer focal length of about 80 inches (2000 mm).
If you can’t decide, there are plenty of compromises between aperture and focal length, but you must be willing to make a few trade-offs regarding the weight of your instrument, the field of view and its ‘power.’ Read on for what you can expect from the three major kinds of telescope: the refractor, reflector and catadioptric.
How does a refractor telescope work?
How do telescopes work? Well, as their name suggests, refractors bend (or refract) the light that they gather to give you a view of your astronomical target. As telescopes go, they have a fairly straightforward assembly and consist of a main objective lens at one end that focuses light through to the other (the bit you look through).
Intuitive to use, the refractor is often a popular choice of instrument for novice astronomers since they require little maintenance and are usually affixed to the simple alt-azimuth mount, which allows the skywatcher to slew from left to right and up and down in order to locate the desired target. Being easy to use means that these telescopes are also simple to manufacture, making them cheaper to buy with price points increasing with aperture size.
Refractors are particularly good at giving highly magnified and high-contrast images. Because of this, they are ideal instruments to use when looking at solar system targets such as the moon and the planets. The best refractors usually have an aperture of two inches (60 mm) or more and will provide reasonable views of astronomical objects. If you’re looking for a larger aperture, then a three- or four-inch (80 mm to 90 mm) will suit you best.
The drawback of a refractor is that they can suffer from chromatic aberration, also known as color fringing. When a single lens doesn’t focus all of the colors emitted from a target object at the same point, bright objects such as the moon, Venus or Jupiter usually have a colored halo around them. Many refractors are manufactured as achromatic or apochromatic (also known as Extra Dispersion (ED) telescopes) to reduce this problem.
The achromatic refractor is cheaper than the apochromatic refractor and, combined with its efficiency, is often the type of telescope that novice astronomers go for. Even if you decide to go for the more expensive achromat, you’re still likely to get a stubborn degree of purple fringing around some targets.
Unless you’re a seasoned skywatcher and you can afford to go for the more expensive apochromat — which corrects for such an effect by using exotic glass for the lenses — this degree of color fringing will not ruin your observing experience to any great extent. If you decide to go for the expensive option, you will be stunned by the views you will get through these excellent telescopes.
Something to consider though: you might find that some apochromats come without a tripod, so you’d need to buy one separately along with any other accessories.
How does a reflector telescope work?
There are two common types of reflector telescope — the Newtonian and the Dobsonian. However, the way these instruments operate is exactly the same — they both use mirrors to reflect light to create an image of the object you’re looking at.
The Newtonian telescope comprises a curved-light collecting mirror, which can be found at the tube’s base. The light that hits this mirror is reflected back to the front of the tube, where a smaller flat mirror — orientated at 45-degrees — brings light to the observer who can see their chosen object.
The Newtonian can be found on alt-azimuth mounts, but you shouldn’t be too surprised to find this type of reflector is more popularly affixed to an equatorial mount, allowing the telescope to follow the rotation of the sky while being aligned with your hemisphere’s celestial pole. This reflector is a favorite in the amateur astronomy community due to its versatility by observing a wide selection of astronomical targets and allowing for astrophotography. With Newtonians, you can also buy a large aperture for less money — for instance, an eight-inch (203.2 mm) reflector would cost you less than a refractor with the same aperture, allowing you to get much more value for your money.
On the downside, the Newtonian doesn’t come hassle-free, especially regarding maintenance. You might find yourself having to have optical mirrors realigned as well as the mirror’s surfaces repainted since they can eventually become tarnished. If you choose to go for a reflector of this sort, you should always choose one with mirrors with a protective coating as they will last longer.
Some beginners to the hobby of astronomy might find setting up and using an equatorial mount tricky and that’s where the Dobsonian comes in. These telescopes give the capabilities of a reflector without the complexities an equatorial mount will bring since it employs an alt-azimuth mount. Dobsonians are very simple to use and can easily be pulled into orientation when looking at astronomical objects. If you’re not confident in navigating your telescope though, then GoTo or computerized Dobsonians and Newtonians (that slew to objects for you) are on the market — but at a higher cost.
Whatever reflector you choose, these telescopes are excellent for low-magnification targets such as galaxies and many types of nebulas.
How does a catadioptric telescope work?
To get the best of both reflectors and refractors, manufacturers developed the Schmidt-Cassegrain and the Maksutov-Cassegrain telescopes. These catadioptric telescopes generally correct issues found in refractors and reflectors.
The Maksutov-Cassegrain corrects the problem that the reflector experiences — an aberration effect called ‘coma,’ which can make objects look distorted and appear like they have a tail. This effect is reduced or banished with the combined efforts of a mirror and a corrector lens. The Maksutov is ideal for beginners or for those who don’t have the time (or money!) to complete any extensive maintenance on their instrument since the tube’s optics are sealed off.
This catadioptric is very robust and is the ideal family telescope. Packed into its short optical tube is a system that allows you to target higher magnification objects such as the planets, moon and double stars. You’ll be able to pick up a Maksutov for a very good price and, if you struggle to find objects and your way around the night sky, then both this type of catadioptric telescope and the Schmidt-Cassegrain can be found in abundance and equipped with a GoTo system.
What you get with a Schmidt-Cassegrain is very similar to the capabilities of the Maksutov. It will allow you to make general observations of planetary targets and stars. It is also possible to expand the telescope’s field of view with the help of corrector lenses, allowing you to view an even wider selection of astronomical targets.
The catadioptric telescope is also suitable if you want to try astrophotography, but combine this with their marked improvement on your standard telescope and you should expect a substantial rise in cost compared to standard reflect and refractors.
How we test the best telescopes
To guarantee you’re getting honest, up-to-date recommendations on the best telescopes to buy here at Space.com we make sure to put every telescope through a rigorous review to fully test each instrument. Each telescope is reviewed based on numerous aspects, from its construction and design, to how well it functions as an optical instrument and its performance in the field.
Our expert staff and knowledgeable freelance contributors thoroughly test each telescope. This ensures honest reviewing based on the telescope’s price, category, and intended use. For example, a 10-inch Dobsonian should not be compared to a 2.76-inch refractor, even though they may be the best in their own class.
We assess the ease of setup of both computerized and motorized mounts, as well as their reliability, accuracy, and noise level. Additionally, we decipher whether a telescope comes with appropriate eyepieces and tripods. We also make suggestions for any additional kits that may be beneficial for the best experience possible.
With complete editorial independence, Space.com are here to ensure you get the best buying advice on telescopes, whether you should purchase an instrument or not, making our buying guides and reviews reliable and transparent.

De nuevo volvemos al ataque. Una semana después de la última salida cargamos otra vez todos los trastos en el coche y salimos de Madrid rumbo sur en busca de cielos oscuros llenos de estrellas. Nos espera una noche bajo las Líridas, las estrellas fugaces del mes de abril, que esta noche tienen su máximo de actividad.
A pesar de que el día había amanecido con algunos chubascos la tarde ya se mostraba totalmente despejada, además no había llovido mucho y los campos acusan la sequía por lo que el poco agua que cayó enseguida fue capturada por el suelo y no había ningún charco. Llegamos al punto de observación en Toledo a la misma hora que la semana pasada y nuestros amigos ya habían llegado e incluso uno de ellos ya tenía montado el telescopio.
Aunque la temperatura era agradable soplaba una ligera brisa que nos acompañó durante la primera mitad de la noche y en algunos casos resultaba algo molesta por producir rachas.
La puesta de Sol fue un espectáculo. El cielo se llenó de infinitas variaciones de tonos azulados que se fundían en el horizonte con otra infinita combinación de anaranjados. Tras el chaparrón de la mañana el cielo estaba muy limpio de nubes aunque se apreciaba que la concentración de polen era altísima.
Una luna creciente de tan sólo 2 días mostraba su tímida sonrisa acompañada de un brillantísimo Venus de la -4,1 iluminado a un 69%. Estuvimos buscando Mercurio pero su tenue brillo de la +3 acompañado del hecho de que al atardecer ya se encontraba bastante bajo nos impidió verlo esta vez como si que hicimos la semana pasada.
Con las últimas luces del día ya empezaban a brillar algunas estrellas, Sirio era la que más destacaba y gracias a esta podíamos encontrar después a Betelgeuse (marcando máximos de brillo en las últimas fechas) y tras ésta podíamos encontrar Rigel y un poco más lejos Castor y Pollux junto a un puntito rojizo que no podía ser otro que el planeta Marte. Estuve disfrutando un rato de estos primeros astros visibles hasta que el vuelo de un mochuelo se cruzó en mi camino y le estuve siguiendo hasta su olivo. Los grillos empezaban a cantar y la banda sonora de la noche arrancaba acompañada de ululatos.
Lo que era un total espectáculo era la Luna, que presentaba una destacada luz cenicienta y se dejaba disfrutar tanto con prismáticos como con telescopio. Una estrella variable doble (HD26128) se deslizó rodando la superficie de la Luna y llegamos a pensar que sería ocultada, cosa que no ocurrió finalmente pero era una maravilla apreciar el movimiento de traslación de nuestro satélite (sumado al de rotación de nuestro planeta) en relación a la estrella.
Después de disfrutar el bocadillo y a eso de las 22:00 empecé la rutina de alineación del telescopio. La idea era empezar la sesión a las 22:38 que marcaba el inicio de la noche astronómica.
En esta ocasión sacaría el color el objeto de la semana pasada, M58 y alrededores. Así que programé dos sets RGB de 150” a bin2 de 12 imágenes cada uno con dithering cada 4 tomas y reenfoque cada 6 imágenes o si había un cambio de filtro.
Una vez funcionando el telescopio ya pude continuar con mi observación visual (si bien cada 15 minutos o así le voy echando un vistazo al telescopio por si pasara algo con el guiado o el enfoque, no hay que confiarse).
Estuvimos observado varios objetos con los prismáticos aunque teniendo el 100mm de “S” y el 12” de nuestro otro compañero al final terminamos mirando más por sus telescopios. Multitud de galaxias como NGC4565 (aguja) o NGC3521 que además de ser muy bonita en fotografías es toda una delicia en visual.
Destacada visibilidad de Líridas
Como esa noche era el máximo de las Líridas por supuesto no pudieron faltar algunos de estos meteoros, la mayoría de ellos muy sutiles y rapidísimos pero otros mucho más brillantes que dejaban una gran estela y parecían muy rasantes. También pudimos ver varios meteoros esporádicos que por su radiante no pertenecían a las Líridas. Entre los 4 que éramos fácilmente vimos unos 30 meteoros y eso que muchas veces andábamos mirando los ordenadores o a través de los telescopios.
Una de las espinitas que me quedó de la última noche fue poder ver el cúmulo de Omega Centauri así que esta vez volví a intentarlo. Me alejé por el camino y subí por unas tierras de labranza en busca de algo más de altura pero nada, debía estar justo oculto por el horizonte de montes que tenía delante. El caso es que ya estaba culminando así que lo tenía difícil para verlo más tarde… no obstante como 1 hora después volví a intentarlo y en esta ocasión tuve más suerte. Un pequeño borroncillo muy difuso era visible rozando el horizonte. Una sonrisa se dibujó en mi cara –“¡Te pillé!”. Y no pude evitar acordarme de un timelapse que unos amigos publicaron en Twitter hace unos días con una captura similar a lo que yo estaba viendo si bien en mi caso el cúmulo estaba más cerca incluso del horizonte.
Otra de las cosas un poco fuera de lo normal que vi esa noche fue un grupo de 3 satélites en formación triangular por la zona de Casiopea, muy bajos en el horizonte. Fue quejarme de ellos en alto y de la cantidad de basura espacial que hay e instantáneamente aparecer otros tres satélites más con la misma formación y en la misma zona, siguiendo a los anteriores ¿Serían Starlink?
Con una agradable noche disfrutada que empezó con 15º y terminamos con 10º, un SQM que llegó a marcar 21.24 y temperatura IR del cielo de -24º dimos por terminada la sesión a las 03:30 ya que al día siguiente teníamos compromisos familiares. Ya en mayo veremos lo que hacemos porque al anochecer más tarde igual empieza a salir a cuenta ir a una casita rural o algo así para aprovechar lo máximo posible. Es lo malo de estas fechas, que las noches cada vez son más cortas.
De momento más que en la próxima salida toca pensar en el Congreso Estatal de Astronomía que se celebra la semana que viene en Zaragoza y donde iremos por primera vez a ver que se desarrolla por allí. Ya os iré contando.
