When setting out to capture images of the night sky for the first time, most people probably start by thinking what sort of camera they need, when in fact making sure you have the right sort of telescope for astrophotography is just as important, if not more so.

And as is the case with visual observing, the best astrophotography telescope for you will depend on what sort of targets you want to photograph.

You will also need to consider what you're going to mount your telescope on, as it will need to track your object as it moves across the sky, and this is especially the case for deep-sky astrophotography where longer exposures are required.

For more on this, read our guide to telescope mounts.

Read on for our guide to everything you need to know to photograph the Moon, the planets and deep-sky objects like galaxies and nebulae, and our pick of some of the best telescopes for astrophotography.

Understanding focal ratio

PrimaLuceLab Airy APO 65F apochromatic refractor review
The PrimaLuceLab Airy APO 65F’s 420mm focal length makes it a relatively fast (f/6.5) instrument.

When choosing a telescope for astrophotography - or, indeed, for visual observing - it pays to consider the focal ratio of the instruments available.

Focal ratio (f-ratio) gives an indication of the ‘speed’ of an optical system: the time it takes your telescope to deliver a set amount of light.

As the f-ratio goes up, so the image scale increases: the object appears larger and consequently dimmer.

So f-ratio is a key value that will help you choose which telescope to use for a specific type of astronomical target.

The f-ratio is defined by dividing your telescope’s focal length by its aperture, using the same units.

So if you have a 100mm refractor with a focal length of 900mm, its f-ratio is said to be f/9.

Adding a 2x Barlow lens increases the effective focal length to 1,800mm and doubles the f-ratio to f/18, but there is a limit to how much focal length is useful.

Telescopes for photographing the Moon

This view of the Moon was captured by John Tipping from Cheshire, UK, 16 May 2019 using a Canon EOS 700D DSLR camera and Sky-Watcher 178mm Maksutov-Cassegrain.

DSLR cameras are a great choice for photographing the Moon, and because they have detachable lenses they can be connected directly to a telescope, turning the scope into the camera lens.

This requires a T-adaptor and a T-ring. The ring mounts on your DSLR and screws into the adapter, which then attaches to your telescope.

For high-resolution lunar imaging, you may want to use a high frame rate planetary camera.

Avani Soares captured amazing close detail on the lunar south pole by using a C14 Edge telescope with a ZWO ASI 290 camera.

You can use any good quality telescope to photograph the Moon, but large aperture Schmidt-Cassegrains and Maksutov-Cassegrains are popular choices with lunar photographers.

Their longer focal lengths are suited to close-up imaging of the Moon, and compared to a high-quality refractor telescope you get a much larger aperture for your money.

Whatever type of telescope you use to photograph the Moon, make sure it’s well collimated if need be.

Your mount should be stable and sturdy and the ability to track the Moon with a motor drive or with a Go-To mount is a must when using a high frame rate camera.

Make sure the drives are tracking at the lunar rate, not the rate at which the stars move across the sky.

Telescopes for photographing planets

Keith Johnson captured this image of Mars before, during and after opposition from Ferryhill, County Durham, UK between 31 August – 30 October 2020. Keith used a ZWO ASI 290MM mono camera and Celestron 9.25-inch Schmidt-Cassegrain on a Sky-Watcher EQ6 Pro mount.

You need a telescope with quite a bit of magnification to photograph surface details on your chosen planet.

To see more detail, you need to increase the magnification or image scale (how big an object appears in the image frame).

This is determined by the focal length of your telescope. As a telescope’s focal length is fixed, you might think that it can only give one magnification, but this isn’t the case.

Optical amplifiers such as a Barlow lens can effectively increase it, while focal reducers effectively lessen it.

Saturn Dmitry Ardashev, Zaprudnya, Moscow region, Russia, 26 July 2021 Equipment: ZWO ASI462MC camera, TS-Optics UNC 10-inch Newtonian, Sky-Watcher EQ6-R mo
Dmitry Ardashev captured this image of Saturn and its rings from Zaprudnya, Russia on 26 July 2021 using a ZWO ASI462MC camera and a TS-Optics UNC 10-inch Newtonian on a Sky-Watcher EQ6-R mount.

In terms of your telescope's focal ratio (see above), large values make the image appear dim and require lower frame rates and longer exposures, and beyond a certain value your telescope won’t be able to deliver any more useful detail.

Under average seeing conditions, figures of f/15-f/25 will probably work best.

If you are lucky enough to experience excellent seeing, values in the f/25-f/45 range can be effective.

A key skill when photographing the planets is knowing how to select the best image scale for the prevailing conditions.

Apertures of 8 inches or larger are best for high-resolution planetary imaging, and the ideal telescope would be a large aperture, long focal length, colour-corrected (apochromatic) refractor.

This kind of scope is great for providing the unobstructed high-contrast views necessary to reveal detail on a planet’s disc.

Uranus and moons Umbriel, Titania, Arial and Oberon photographed by Harvey Scoot, Essex, UK using a C14 Edge HD telescope and ZWO120MMS camera.

Reflecting telescopes can also be excellent planetary scopes, but to get high image scales you need a long focal length instrument.

As aperture increases, such an instrument can become heavy and cumbersome, making it difficult to mount and handle.

One popular design for planetary astrophotography is the catadioptric scope, which uses both mirrors and lenses.

The Schmidt-Cassegrain design balances size and performance with affordable cost.

And since the optics of this kind of scope effectively ‘fold’ the light path, a large aperture, long focal length Schmidt-Cassegrain is also fairly easy to handle.

Saturn John Chumack, Dayton, Ohio, USA, 20 August 2021 Equipment: ZWO ASI224MC camera, Celestron C11 Schmidt-Cassegrain
Saturn photographed by John Chumack, Dayton, Ohio, USA, 20 August 2021 using a ZWO ASI224MC camera and a Celestron C11 Schmidt-Cassegrain.

You’ll also need a solid mount for planetary imaging. Ideally an equatorial design, polar aligned with driven right ascension and declination axes.

If you have a smaller telescope, don’t worry: telescopes under 8 inches in aperture are capable of capturing some detailed shots under the right conditions.

The key is to keep the image scale realistic for the size of the scope and conditions.

A family portrait of Jupiter with its four Galilean moons, for example, can be just as stunning as a close-up.

Telescopes for photographing galaxies

It’s a common assumption that you need a large and powerful telescope for deep-sky imaging.

Since many deep-sky objects are rather large, smaller, short focal length telescopes with wider fields of view can be very effective, especially for regions of nebulosity that are particularly extensive.

The Pinwheel Galaxy, Rouzbeh Bidishahri, Vancouver, Canada, 10 June 2021. Equipment: QHY268M camera, Planewave CDK12.5 astrograph, Astro-Physics 1100 GTO mount
The Pinwheel Galaxy, photographed by Rouzbeh Bidishahri, Vancouver, Canada, 10 June 2021 using a QHY268M camera and Planewave CDK12.5 astrograph on an Astro-Physics 1100 GTO mount.

Although the old adage 'there’s no substitute for aperture' is valid for observing deep-sky objects, it’s not quite so important for imaging, as you can compensate for smaller apertures with longer exposures.

The larger the telescope, the greater the loading on the mount; the heavier the load, the more work the mount will have to do to track properly.

Longer focal lengths will also put greater demands on a mount’s tracking abilities.

Small tracking errors are amplified by long focal lengths, so choose your telescope carefully to get the most from your system and to ensure that your mount and telescope are well matched.

If your main interest lies in galaxies and globular clusters, then their relatively small apparent size will mean that a longer focal length telescope is a good choice to photography them in detail, so consider a Schmidt-Cassegrain instrument or Newtonian reflector.

These objects do look great in a wider field of view, though, which enables you to see them in a wider setting.

Telescopes for photographing nebulae

The North America Nebula by Rachael and Jonathan Wood, Doncaster, 15 June 2021. Equipment: ZWO ASI294MC Pro camera, Sky-Watcher Evostar ED80 refractor, Sky-Watcher HEQ5 Pro mount

If your interests are more nebula-based, a short focal length refractor would be a good choice for photographing nebulae. Many deep-sky imagers find a 3- or 4-inch refractor perfect for this purpose.

The advantage of using a small refractor is that it will place fewer demands on your mount, both in terms of load-bearing and tracking performance.

This is why many established imagers recommend these instruments to people starting out on the imaging road.

Can one telescope do all astrophotography?

If your interests are polarised between planetary or lunar observations and deep-sky imaging, a Schmidt-Cassegrain with a focal reducer-field flattener will cover a lot of the astrophotography ground.

Armed with this knowledge, it's time to take the plunge! But which are the best telescopes for astrophotography?

We've reviewed quite a lot of telescopes over the years, and below we've picked out some of the best astrophotography telescopes for beginners and experienced imagers alike.

Best telescopes for astrophotography

1

Celestron 114LCM computerised telescope

Celestron 114LCM computerised telescope

The Celestron 114LCM has a 4.5-inch mirror and a focal length of 1,000mm giving a focal ratio of f/9.

The 114LCM makes for a great planetary imager. We were able to capture a wonderful image showing Saturn and a crisp view of its majestic rings.

Turning to the Moon, we were able to undertake an 8-panel Moon mosaic showing off great detail on the lunar surface.

The 114LCM is not suited to deep-sky imaging, but is certainly one to go for if your interestes lie closer to home, within our Solar System.

It offers good optics and a computerised mount that can point straight to your chosen target with the touch of a button.

Tecnosky AG70 astrograph

Tecnosky AG70 astrograph review

The TecnoSky AG70 is designed to help astrophotographers capture images with as little fuss as possible, and it goes along way to fulfilling this brief.

It has an optical system designed to eliminate issues with star shapes and colour problems and removes the need to use a coma corrector.

The AG70 has a focal length of 350mm, making it great for capturing extended objects and large nebulae. A fast f/5 focal ratio allows for short exposures, which is good news for those using DSLR cameras.

Plus, considering the AG70 measures just 310mm and weighs 2kg, it's a portable telescope, making it a good option for astrophotography sessions in far-flung sites.

Read our full Tecnosky AG70 astrograph telescope review.

SharpStar SCA260 Aspherical Cassegrain Astrograph

SharpStar SCA260 Aspherical Cassegrain Astrograph scale

At over 700mm long and 280mm wide and weighing 15kg - without camera or guiding equipment - this is a serious instrument for dedicated astrophotographers, but among other similar telescopes it boasts a relatively low price tag.

Its optical arrangement makes the SCA260 suitable for a wide range of astrophotography cameras.

Using a full frame colour CMOS, we were able to capture a large target like the Pleiades in its entirety, with beautiful diffraction spikes on the brightest stars.

Turning to a smaller sensor camera we got lovely images of galaxies like NGC 891. It's these sorts of images that first got us interested in astro imaging.

Smaller deep-sky objects like the Cigar Galaxy and the Dumbbell Nebula showed good detail and a close-up field of view.

Explore Scientific ED127 apo refractor

Explore Scientific ED127 apochromat refractor
  • Buy now from B&H

The ED127’s air-spaced triplet is ideal for getting good views of faint deep-sky objects and for finer details on the planets and the Moon.

A focal length of 952mm gives it a focal ratio of f/7.5.

During our imaging run we found good consistency across a non-full frame DSLR sensor at prime focus.

The ED127 also makes for a good medium-resolution planetary imaging instrument, and we acquired some lovely detail in our lunar images when paired with a high frame rate camera.

We photographed the lunar surface at prime focus through a red, green and blue filter without re-focusing between filters.

We were impressed with the results: combining individually filtered data didn’t introduce any noticeable colour fringing.

Unistellar eVscope eQuinox

Unistellar eVscope eQuinox telescope review.

At its core, the Unistella eVsccope eQuinox is a cool piece of kit that effortlessly produces images of the night sky and sends them to your smartphone or tablet.

If you're not interested in learning the fundamentals of observing with a telescope or fiddling with camera settings, but simply want a great piece of technology that will give you beautiful captures of deep-sky objects, this could be the telescope for you, provided the price tag doesn't put you off.

The eVscope eQuinox is a 4.5-inch, f/4 reflector with a camera sensor that tracks and stacks images in real-time to produce the final image.

Yes, it will even do image processing for you.

Everything is done via the app, so you will need a tablet or smartphone. Up to 10 devices can be linked to the telescope over Wi-Fi, making it a good option for astronomy outreach or star parties.

The app asks whether you're in a city, suburb or countryside, then recommends targets suited to your surroundings.

The Ring Nebula looked bright and colourful after just 24 seconds. The Andromeda Galaxy was similarly inspiring.

The images produced by the eQuinox do ultimately fall short of those produced by astrophotographers using cameras on dedicated telescopes, but if you're interested in this sort of telescope, the ease and gadgetry involved will more than likely make up for it.

Founder Optics FOT106 triplet refractor

Founder Optics FOT106 triplet refractor review

The FOT106 has an f/6 106mm objective lens with a focal length of 636mm, putting it in the realms of being able to image larger star clusters, galaxies and nebulae.

The balance point of the tube is fairly central, which makes it easy to mount for astrophotography.

During our imaging session we attached a field-flattener to our DSLR camera T-Ring via the M48 adaptor option provided.

We photographed star-rich areas and found central stars were round and pin-sharp.

We reckon a crop area of about 70% of full-frame size would produce acceptable star shapes, making it about right for DSLR and CMOS cameras with APS-C-size sensors or smaller.

Read our full Founder Optics FOT106 triplet refractor review.

Celestron 11-inch Rowe-Ackermann Schmidt astrograph

Celestron 11-inch Rowe-Ackermann Schmidt astrograph

Celestron’s Rowe-Ackermann Schmidt astrograph is made specifically with the sole purpose of imaging the night sky, so if this is your number one aim, you're in good hands.

Dividing its 620mm focal length by its 279mm (11-inch) aperture shows it to be a fast f/2.22 telescope.

The best camera to use with the RASA would be a CCD camera with a low circular profile, so it's hidden behind the adaptor plate. But DSLRs can be used too.

During our imaging session we were able to go deep very quickly.

Within 5 seconds at ISO 1600 we captured a huge amount of detail in and around the Orion Nebula.

This is another large, hefty telescope at a costly price, but is certainly a good option for those who are serious about astrophotography.

Altair Starwave 70 EDQ-R quad apo imaging refractor

Altair Starwave 70 EDQ-R quad apo imaging refractor

The Starwave 70 EDQ-R has a 350mm, f/5 focal length and is aimed at wide-field imaging.

Indeed, given the right camera it is able to fit some really big objects into its field of view.

What's more, this telescope is very user-friendly. Much of this is down to just how light it is: even with a Canon DSLR attached it weighed around 2kg, making it a good grab-and-go scope.

We imaged the Andromeda Galaxy with a finder-guider configuration on a portable tracking mount.

3x20-minute images revealed lots of detail in the dust lanes and round, colourful stars. We were very happy with the result.

Stellina Observation Station

Stellina Observation Station

The Stellina is another cool piece of kit that offers to take all the manual tinkering out of astrophotography, automatically capturing images of deep-sky targets without the need for guiders, mounts, computer software, or even an external camera.

Assembly is easy and we were able to capture a range of targets including the Orion Nebula, the Cigar Galaxy, the Crab Nebula and the Andromeda Galaxy.

Again, like the eVscope, this is an all-in-one device that takes the hassle out of imaging the night sky, but it also removes the element of control.

If you want to be able to manually control every aspect of your astro imaging session, it's not for you.

But if you want a nifty piece of tech that will do everything for you and leave you with beautiful images, this could be the one to go for.

William Optics Zenithstar 126 apo refractor

William Optics Zenithstar 126 apo refractor

A lightweight, portable scope, the ZS61-II boasts a 61mm objective lens with a focal length of 360mm, giving it a mid-range focal ratio of f/5.9.

The scope can be used for capturing images of the Moon and planets and - with the correct solar filter attached - the Sun.

During our imaging sessions, the Bahtinov mask provided in the dew shield really helped with reaching accurate focus.

This is also a result of the ZS61-II’s dual-speed rack and pinion focuser, which is positive and responsive.

Overall, this is great visual telescope but can also be used for imaging, while its portability makes it a good option for travelling to dark-sky sites.

Omegon Telescope Pro RC 203/1624 review

Omegon Telescope Pro RC 203/1624 review

The Omegon Telescope Pro RC 203/1624 is aimed at experienced astrophotographers.

We began our imaging session with the Hercules Globular Cluster, taking a series of 5- and 10-minute exposures that revealed sharp details and colour at the core, continuing to the outer edges as well.

The Dumbbell Nebula and the Whirlpool Galaxy were similarly impressive.

When our 15-minute exposure of the Whale Galaxy appeared on the screen it was a real 'wow!' moment.

We found a bright galactic core and beautifully defined dark dust lanes, all captured with crisp sharpness.

Read our full Omegon Telescope Pro RC 203/1624 review.

TS 65mm f/6.5 Quadruplet Astrograph

TS 65mm f6.5 Quadruplet Astrograph

The Teleskop-Service 65mm Quadruplet Astrograph has 2-inch rack-and-pinion focuser that's well-made and securely held our camera and astro imaging kit with no slippage, even with the tube pointing up towards the zenith.

The multicoated 65mm aperture, f/6.5 triplet lens has a focal length of just 420mm. This makes for a 3° by 2° field with the typical APS-C size sensor found in DSLR cameras.

This field of view would hold Orion’s ‘belt’ stars. During our star test we captured Vega and were really impressed.

It showed excellent star shapes at the centre and into the corners of our CCD camera's field of view.

We then turned to the Milky Way and captured the nebulosity around the star Sadr in Cygnus. We were very impressed with this telescope.

Read our full TS 65mm f/6.5 Quadruplet Astrograph review.

Altair 8-inch F4 Photo Newtonian Telescope

Altair 8-inch F4 Photo Newtonian Telescope review

This reflecting telescope from Altair is designed to be used for astrophotography.

It's a sturdy steel tube with rings and fittings and weighs about 8.4kg even without astro imaging equipment attached. As a result, you'll need a very strong, good mount to make the most of its light-gathering power.

We imaged the Dumbbell Nebula, using the surrounding star field to check star shapes, which looked good right into the corners of the view.

We proceeded with short 5-minute exposures and were reminded why fast Newtonian imaging astrographs are so attractive to astrophotographers.

Experienced astrophotographers might frown at our inclusion of the Celestron Inspire 100AZ in this list of best telescopes for astrophotography, but for complete beginners who want a good value scope that will let them capture images on their smartphone, this is a great choice.

It's worth remembering that the Inspire 100AZ's non-motorised mount is not designed with astrophotography in mind, but the telescope's dust cap enables a smartphone to be attached that can then be paired with one of the included eyepieces for a spot of afocal photography.

We were able to capture a video of the Moon through the 20mm eyepiece, which we then stacked into a single image.

You could do the same with the Sun, provided you used a suitable front-mounted solar filter.

If you're a beginner looking to buy your first telescope and you'd like to have a go at smartphone astrophotography, this might be the model for you.

Read our full Celestron Inspire 100AZ refractor review.

Sky-Watcher Evostar 72 refractor

Sky-Watcher Evostar 72ED DS-Pro refractor telescope

This is another great budget telescope that won't break the bank but will provide great visual observing as well as imaging capabilities.

What's more, it's nice and compact, making it another good option for those who want a reliable imaging telescope to take to dark-sky sites.

We used our Star Adventurer tracking mount to capture M44 with 13x30-second exposures, and the results were satisfying.

Then we used our AZ-EQ6 mount to photograph M81 and 82 using 12x120-second exposures. We achieved great detail in our images and were thoroughly pleased with the results.

The Evostar 72ED DS-Pro is a satisfying, lightweight scope great for observing the night sky as well as for astrophotography.

Vixen R200SS Newtonian reflector

Vixen R200SS Newtonian reflector

Those reading this article in the UK will be all too aware of how unpredictable and temperamental the weather can be.

This makes a fast scope with good aperture that's easy to set up very appealing, and the Vixen R200SS certainly fits into this bracket.

We tested the telescope out with a DSLR camera and Bahtinov mask and we found the focus was crisp across the entire field of view.

The corrector keeps good colour across the red, green and blue wavelengths, so if you're imaging with a DSLR or CCD camera, you won't be plagued by bloated blue stars.

We found the images produced from the R200SS and Corrector PH in combination were brilliant, and enjoyed seeing sharp, well-shaped stars even at the edges of the frame.

Read our full Vixen R200SS Newtonian reflector plus Corrector PH review.

Meade LX600-ACF 12-inch Schmidt-Cassegrain

How to collimate a Schmidt-Cassegrain telescope

The included sturdy field tripod and optional Meade X-Wedge make this a solid, sturdy platform suitable for long-exposure imaging.

We liked the StarLock feature, which gives the astrophotographer precision pointing accuracy as well as autoguiding functionality.

The LX600 really shines when used for planetary imaging, as the StarLock helps keep the target in the middle of the field of view.

Indeed, this is a scope that particularly suits those who like producing planetary time-lapses.

The generous 2.4m focal length offers good image scale without an optical amplifier.

In summary, this is a formidable astro-imaging platform.

Read our full Meade LX600-ACF 12-inch Schmidt-Cassegrain review.

RVO Horizon 60ED Doublet refractor

RVO Horizon 72ED refractor review

A key aspect of the Horizon 60ED is its portability. The telescope is supplied in a sturdy case that houses the entire assembly, so the only extras you need for an imaging session in a dark-sky site are a DSLR and a good mount.

The whole setup including DSLR weighs less than 3kg, so could easily be supported by most star-tracking mounts.

We captured images of Orion and found them to be remarkably good, particularly given our full-frame camera.

The Horizon 60ED refractor is a good value, capable astrophotography telescope with the added bonus of coming in a portable package.

Read our full RVO Horizon 60ED Doublet refractor review.

19

William Optics GTF 102 astrograph

William Optics GTF 102 five element astrograph

We used a CCD camera with an APS-C sensor to test the WO GTF 102, so the star shapes in our images are a good sign as to what you might expect to achieve with a typical DSLR camera, which has a similarly sized sensor.

The shape of stars across the field of view were beautiful, even right into the corners. Clearly the two-element internal field flattener was doing its job.

The same can be said for the triplet lens, as chromatic aberration was also well controlled.

Multi-element designs like this can sometimes cause focus shift as the temperature changes.

But we didn't need to adjust focus during a 4.5-hour astrophotography run, despite the presence of a thick frost on the inside of our domed garden observatory.

We would recommend the WO GTF 102 to any astro imager who wants a well-performing instrument that removes the hassle of achieving a flat field with stars pin sharp to the edge.

Celestron RASA-8 telescope

Celestron RASA-8 telescope
  • Buy now from B&H

Like other astrographs on our list, the Rowe -Ackermann Schmidt Astrograph is primarily designed for astrophotography.

The RASA-8 has an effective focal length of 400mm and an aperture of 203mm, so its focal ratio is f/2.

In astrophotography terms, f/2 is fast, indicating it can capture deep-sky images very quickly.

We found we could reach serious depth with short exposures: our Atik 314L+ cooled CCD camera was able to reach mag. +15 in one second.

And under challenging skies we were able to capture mag. +17.5 galaxies with 30-second exposures.

A 30 second image of the Leo Triplet, for example, recorded great detail in each galaxy.

This is a great grab-and-go instrument for deep-sky astrophotography.

Explore Scientific PN210 Carbon Mk II Imaging Newtonian review

Explore Scientific Carbon-Fiber PN-210800 Newtonian reflector

The PN210 Mk II is a grab-and-go telescope with great portability. Its fast f/3.8 optics enable you to capture real depth with short exposures.

This is due to the 210mm parabolic primary mirror at the heart of the telescope.

The PN210 Mk II is easy to transport to a dark-sky location, meaning you can take advantage of those optimum conditions to capture some great deep-sky images.

The 800mm focal length of the primary mirror delivers a fairly wide field of view at prime focus.

We used a Canon EOS 6D full frame DSLR camera and were able to cover a sky area of 2.5x1.5° with our images.

However, we would recommend using a field flattener. Being a Newtonian reflector, the PN210’s field does suffer from coma.

Despite this, this is a great telescope that will perform well for deep-sky imagers.

StellaMira 90mm ED triplet apochromatic refractor

StellaMira 90mm ED triplet refractor

The 90mm lens of the StellaMira 90 offers a 540mm focal length, which gives it a fast f/6, making it suited to astrophotography.

We used a CCD camera and DSLR to test out the telescope, and found round and sharp stars.

We particularly liked the focuser arrangement: the whole focuser body rotates, allowing control knobs to be conveniently placed while a separate camera rotator allows adjustment of the camera angle.

We found the hot blue stars of the Pleiades and the tight star grouping of the Trapezium Cluster to be beautifully crisp and free of unwanted artefacts.

The StellaMira 90mm ED produces excellent astro imaging results.
