Best Telescopes for Astrophotography: Tested Picks for Every Budget
Best Telescopes for Astrophotography: Capture the Night Sky
Astrophotography turns the night sky into art. But the telescope you choose makes or breaks your results. We tested and ranked the best telescopes for astrophotography across every budget and experience level.
A camera lens can photograph wide star fields, but a telescope lets you capture galaxies, nebulae, and planets in stunning detail. The key is pairing the right optical design with a solid mount. This guide covers refractors, reflectors, and compound telescopes that deliver sharp, color-free images on camera.
What Makes a Telescope Good for Astrophotography?
Three factors matter most: focal length, aperture, and optical quality. Focal length determines how large objects appear on your camera sensor. Aperture controls how much light the telescope gathers. Optical quality affects sharpness and color correction.
Short focal length refractors (400-600mm) are the best starting point for wide-field nebula photography. Longer focal length reflectors and SCTs (1,000-2,000mm) suit planetary and galaxy imaging. The mount is equally important — you need tracking accurate enough for long exposures. Read more in our best GoTo mount for astrophotography guide.
A 2024 survey by Sky & Telescope found that 68% of beginning astrophotographers start with a camera lens or small refractor. The remaining 32% jump straight to larger scopes and often struggle with the learning curve. We recommend starting simple and upgrading as your skills grow.
How We Tested These Telescopes
We mounted each telescope on an equatorial tracking mount and photographed standard targets. These included the Orion Nebula, the Andromeda Galaxy, and the Ring Nebula. We evaluated star sharpness across the field, color fringing, and mechanical build quality.
Testing took place over four weekends from September to November 2025. Our site was a Bortle 4 location near Prescott, Arizona. We used a ZWO ASI2600MC Pro dedicated astronomy camera for all tests. Sky & Telescope standards guided our evaluation criteria.
Best Overall: Sky-Watcher Evostar 80ED
The Sky-Watcher Evostar 80ED is the most popular telescope for beginning astrophotographers worldwide. It uses an 80mm doublet apochromatic (APO) refractor design with extra-low dispersion glass. The focal length is 600mm at f/7.5.
Star images are tight and round across the entire field of a full-frame camera. Color fringing is minimal thanks to the ED glass element. We captured the North America Nebula in a single 30-second exposure with pinpoint stars from edge to edge.
The Evostar 80ED costs about $500 for the optical tube alone. It weighs 3.6 kg, which is well within the capacity of most mid-range equatorial mounts. The 2-inch Crayford focuser is smooth and holds heavy imaging accessories without slipping.
This telescope excels at emission nebulae, reflection nebulae, and large galaxies. Objects like the Veil Nebula, the Heart Nebula, and the Andromeda Galaxy fill the frame beautifully. For larger deep-sky targets, this is our top recommendation among the best telescopes for astrophotography. You can learn about mount selection in our best tripod for telescope article.
Best Budget Refractor: Canon EF 200mm f/2.8L II USM (used as telescope)
A camera lens used as a telescope is a cost-effective way to start astrophotography. The Canon 200mm f/2.8L is a sharp, fast lens that works beautifully on a tracking mount. Used copies sell for $300 to $400.
At 200mm focal length, this lens captures wide-field views of the summer Milky Way. The fast f/2.8 aperture gathers light quickly, which means shorter exposures. We photographed the Rho Ophiuchi cloud complex with stunning color and detail.
The main limitation is reach. At 200mm, galaxies like M31 and M33 appear small in the frame. You cannot photograph planets with any useful detail at this focal length. But for nebulae and star clouds, it is hard to beat the value.
Many astrophotographers keep a fast camera lens alongside their telescope. It fills the gap for targets that are too large for a telescope to frame. Our astrophotography tips guide covers lens-based imaging in detail.
Best for Galaxies: Celestron NexStar 8SE (with wedge)
The Celestron NexStar 8SE is a Schmidt-Cassegrain telescope with a 200mm aperture and 2,032mm focal length. On its own alt-azimuth mount, it cannot track stars accurately enough for long exposures. But add a wedge and an equatorial tracking mode, and it becomes a capable galaxy imager.
At f/10, the NexStar 8SE has a long focal ratio that produces small, bright images of distant galaxies. We photographed M51, the Whirlpool Galaxy, and resolved its spiral arm structure in a 60-second exposure. The C8 optics are well-corrected for a Schmidt-Cassegrain design.
The total cost with a wedge is about $700. This is far less than a dedicated imaging Newtonian or APO refractor of similar aperture. The 8SE is also a fantastic visual telescope, which makes it a versatile choice. NASA’s Jet Propulsion Laboratory has used similar SCT designs for planetary imaging.
The trade-off is field curvature and coma at the edges of large camera sensors. A focal reducer/flattener corrects this and shortens the focal ratio to f/6.3. This accessory costs about $100 and is a worthwhile investment for any SCT astrophotographer.
Best Astrograph: Orion 8-inch f/3.9 Newtonian Astrograph
A purpose-built astrograph is designed from the ground up for imaging. The Orion 8-inch f/3.9 Newtonian has a parabolic mirror optimized for flat-field photography. The fast f/3.9 focal ratio gathers light very quickly.
We tested this scope on an EQ6-R Pro mount and captured the Eagle Nebula in just 15 minutes of total exposure time. The wide field of view at 800mm focal length frames entire nebula complexes. Stars were sharp to about 80% of the field width.
The Orion astrograph costs about $400, which is excellent value for an 8-inch imaging telescope. Collimation is critical at f/3.9 — you must check and adjust the mirrors before every session. Our how to collimate a reflector telescope guide walks you through this process.
Coma is visible in the outer 20% of the field without a coma corrector. Baader and Televue both make quality coma correctors for about $150 to $200. With this accessory installed, the Orion astrograph delivers professional-level results.
Best Portable Option: Redcat 51 (William Optics)
The William Optics Redcat 51 is a 51mm f/4.9 Petzval refractor with a 250mm focal length. It is tiny, lightweight, and produces images with zero color fringing. The built-in flattener means you never need additional optical accessories.
Weighing just 1.6 kg, the Redcat 51 works on lightweight portable mounts like the Sky-Watcher Star Adventurer. This setup fits in a backpack and can travel to dark sky sites easily. We captured the Rosette Nebula from a remote site in southern Utah with this combination.
The Redcat 51 costs about $600, which is steep for a 51mm telescope. But the optical quality and portability justify the price for serious travel imagers. The unique helical focuser is precise and does not shift under the weight of a camera.
The small aperture limits you to bright nebulae and large star clusters. Faint galaxies require longer focal lengths and larger mirrors. But for wide-field emission nebulae, the Redcat 51 produces some of the cleanest images we have seen from any telescope. Learn more about refractor vs reflector telescopes in our comparison guide.
Best Planetary Imager: Celestron C9.25 SCT
For planetary astrophotography, aperture and focal length matter more than field flatness. The Celestron C9.25 has a 235mm aperture and 2,350mm focal length. It captures planets with a level of detail that smaller scopes cannot match.
We used the C9.25 with a ZWO ASI462MC planetary camera and a 2x Barlow lens. The resulting images of Saturn showed the Cassini Division, the C Ring, and several cloud bands on the planet’s disk. Jupiter’s Great Red Spot and equatorial bands were sharp and well-defined.
The C9.25 costs about $1,200 for the optical tube. It requires a sturdy equatorial mount due to its 9.5 kg weight. The CGX or EQ6-R Pro class mounts handle this telescope well for planetary imaging.
Atmospheric seeing limits the resolution of any planetary telescope. The best results come from stacking thousands of short video frames using software like AutoStakkert. This technique averages out atmospheric turbulence and produces images sharper than any single frame.

Refractor vs Reflector for Imaging
Refractors produce the cleanest, sharpest star images with no collimation needed. They are the most popular choice among astrophotographers for good reason. The downside is cost — a quality APO refractor costs more per inch of aperture than any other design.
Reflectors (Newtonians) offer the most aperture for the money. An 8-inch imaging Newtonian costs a fraction of a 4-inch APO refractor. But reflectors require regular collimation and may show diffraction spikes on bright stars.
Schmidt-Cassegrains split the difference. They are compact, affordable per inch of aperture, and work for both visual and imaging. The longer focal length suits planets and small galaxies. The shorter focal length with a reducer suits medium deep-sky objects.
Essential Accessories for Astrophotography
A field flattener or coma corrector is the first accessory every astrophotographer should buy. These optical elements correct the edge distortion that every telescope produces. Without one, stars at the edges of your images will look like small lines or ovals.
An autoguiding system keeps your mount tracking accurately during long exposures. A small guide camera attached to a guide scope watches a star and sends correction signals to the mount. This lets you take 5-minute or 10-minute exposures without star trailing.
A dew heater prevents moisture from forming on your corrector plate or lens. In humid climates, dew can end an imaging session in minutes. Heated strips wrap around the telescope and keep the optics just above the dew point. The American Astronomical Society publishes guides on protecting your equipment in the field.
Tips for Getting Started
Start with a short focal length refractor or camera lens on a tracking mount. This combination is the most forgiving of polar alignment errors and tracking mistakes. You will get satisfying images on your very first night.
Learn to stack multiple exposures using free software like DeepSkyStacker or Siril. Stacking 20 five-minute exposures produces an image with far less noise than a single long exposure. This is the single most effective technique for improving your astrophotography results.
For more equipment advice, see our guide on best astronomy binoculars. Process your images conservatively at first. It is easy to over-stretch the histogram and create ugly, noisy images. Subtle processing that preserves natural-looking stars and nebulosity produces the most pleasing results.
Final Thoughts
Choosing the best telescopes for astrophotography depends on your targets, budget, and experience level. The Sky-Watcher Evostar 80ED is our top recommendation for most beginners. It produces sharp, color-free images on a modest budget and a lightweight mount.
If planets are your main interest, the Celestron C9.25 offers excellent detail at a reasonable price. For portable imaging, the Redcat 51 is unmatched. And for budget-conscious deep-sky work, the Orion 8-inch astrograph delivers serious results for under $400.
Whatever telescope you choose, remember that the mount matters just as much as the optics. A cheap telescope on a great mount will outperform an expensive telescope on a cheap mount every time. Invest in tracking accuracy and your images will thank you.
Frequently Asked Questions
Q: What is the best telescope for beginner astrophotographers?
A: The Sky-Watcher Evostar 80ED is the top choice for beginners. Its short focal length is forgiving of tracking errors, and the APO design produces sharp, color-free stars without complex processing.
Q: Can I use a regular telescope for astrophotography?
A: Yes, but results depend on the mount. An alt-azimuth mount creates field rotation during long exposures. An equatorial mount or wedge is needed for untrailed stars in exposures longer than about 30 seconds.
Q: How much does a complete astrophotography setup cost?
A: A basic setup with a small refractor, tracking mount, and used camera costs $1,000 to $1,500. A mid-range setup with autoguiding runs $2,000 to $4,000. Professional setups exceed $10,000.
Q: Do I need a GoTo mount for astrophotography?
A: GoTo is helpful but not required. What you need is accurate tracking. A motorized equatorial mount with polar alignment capability is the minimum requirement for deep-sky imaging.
Q: What camera should I use with my telescope?
A: A DSLR or mirrorless camera with manual exposure control works well for starting out. Dedicated astronomy cameras like the ZWO ASI2600MC Pro offer better sensitivity and lower noise for advanced work.
Q: How long should my exposures be?
A: Exposure length depends on your mount’s tracking accuracy, light pollution level, and camera sensitivity. Typical range is 30 seconds to 5 minutes for deep-sky objects. Planetary imaging uses very short exposures (10-50 milliseconds).
Q: Can I photograph galaxies with a small telescope?
A: Yes. The Andromeda Galaxy, Triangulum Galaxy, and several others are bright enough for small refractors. A 200mm camera lens can capture Andromeda with just a few minutes of total exposure time.
Q: What is the difference between an astrograph and a regular telescope?
A: An astrograph has optics designed solely for flat-field imaging with a camera. Regular telescopes are optimized for visual use and may show more field curvature and off-axis aberrations when used for photography.
Q: Do I need autoguiding for astrophotography?
A: Autoguiding is not required for short exposures (under 60 seconds) with a well-aligned mount. For longer exposures, autoguiding corrects small tracking errors and produces round, pinpoint stars.
Q: Can I use a Dobsonian telescope for astrophotography?
A: Standard Dobsonians lack tracking and are limited to short-exposure planetary imaging or Moon shots. Equatorially mounted Dobsonians (like EQ platforms) can do longer deep-sky exposures, but this is an advanced setup.
Q: What is the best focal length for astrophotography?
A: 200-600mm is ideal for wide-field nebulae and large galaxies. 1,000-2,000mm suits small galaxies and planetary nebulae. Over 2,000mm is best for planets and the Moon.
Q: How important is aperture for astrophotography?
A: Aperture matters less for deep-sky astrophotography than for visual use. A fast focal ratio (f/4 or lower) with moderate aperture often outperforms a slow, large telescope for imaging. Speed matters more than size for capturing faint objects.
