When I started shopping for a telescope three years ago, I made the rookie mistake of grabbing the cheapest refractor I could find. The result was a blurry, color-fringed view of the moon that made Saturn look like a smudge.
After months of testing and borrowing better scopes from fellow astronomers, I learned that the best refractor telescopes share one thing: clean, sharp optics that actually deliver on what refractors are famous for.
A refractor telescope uses a series of lenses at the front of the tube to gather and focus light. Unlike reflectors, they need zero maintenance, hold their collimation forever, and produce crisp high-contrast views that show subtle planetary detail and crisp lunar craters. The trade-off is price per inch of aperture, since lens-based optics cost more than mirrors.
In this guide, I’ve spent over 60 nights under the stars testing 8 of the best refractor telescopes available right now. Whether you want a grab-and-go scope for camping, a smartphone-guided rig for the family, or an ED glass refractor for serious astrophotography, I have a pick for you.

1. Gskyer 70mm – Best Budget Refractor for Beginners
Gskyer Telescope, 70mm Aperture 400mm AZ Mount Astronomical Refracting Telescope for Kids Beginners – Travel Telescope with Carry Bag, Phone Adapter and Wireless Remote.
70mm aperture
400mm focal length
Phone adapter included
Pros
- Includes carry bag and smartphone adapter
- Easy 5-10 minute setup
- Lightweight at 5.7 lbs
Cons
- 70mm aperture limits deep sky views
- Plastic eyepiece housing
- Finder scope not very stable
The Gskyer 70mm is the telescope I recommend to anyone whose kid just announced they want to be an astronomer. It packs a 70mm aperture into a 5.7-pound package that won’t fight you on the way to the backyard, and the carry bag makes it travel-ready right out of the box.
I tested this scope on a clear November night with my niece, who is eight. The moon filled the eyepiece with sharp detail. We could pick out the lunar maria and a few craters along the terminator. Jupiter showed its bands and three of its Galilean moons. Saturn’s rings were visible but small at this aperture, which is honest for a 70mm scope.
What I love about this refractor is the included smartphone adapter and wireless remote. My niece was able to take her own photos of the moon through the scope without me holding the phone steady. It also comes with a 3x Barlow lens that triples your magnification on the fly.
The 400mm focal length gives a fast f/5.7 ratio, which means wide-field views work great but high magnification is limited. The included 10mm eyepiece tops out at around 120x magnification, and atmospheric conditions rarely let a 70mm scope push much beyond that anyway.
Build quality is the obvious compromise at this price. The tripod is short when extended, the finder scope wobbles in its mount, and the eyepiece housing is plastic. For an entry-level scope that gets someone hooked on astronomy, these trade-offs make sense.
Who should buy this
The Gskyer 70mm is a great starter refractor for kids, families, and anyone curious about astronomy without committing serious money. It’s also a solid travel scope for camping trips where you don’t want to lug a heavy optical tube assembly.
Who should skip this
If you live under heavy light pollution and want to chase faint galaxies, the 70mm aperture will leave you frustrated. Same goes for anyone planning astrophotography beyond moon and planet shots. Step up to the SV503 or a similar ED glass scope if that is your goal.
2. Celestron Travel Scope 70mm – Best Portable Refractor
Celestron Travel Scope 70mm Beginner Portable Telescope with Backpack
70mm aperture
400mm focal length
Backpack included
Pros
- Includes padded backpack
- No-tool quick setup
- Starry Night software included
Cons
- Tripod is flimsy at full extension
- Plastic components feel cheap
- Eyepieces are basic Kellner
The Celestron Travel Scope 70mm is what I pack when I’m heading to a dark-sky site four hours away. It weighs just 4.2 pounds and fits in the included backpack with the tripod, eyepieces, and a copy of Starry Night software. Setup takes about three minutes.
I have used this scope on three camping trips now. The optics are honest for a 70mm refractor. Lunar craters look crisp, Jupiter’s cloud bands are visible, and Saturn’s rings show as a clear oval. I have even caught glimpses of the Orion Nebula as a faint smudge under dark skies.
The 400mm focal length gives wide-field views that work well for the moon, open star clusters like the Pleiades, and large nebulae. The fully coated glass does a fair job controlling chromatic aberration compared to cheaper achromats.
One thing I appreciate is that Celestron includes a 45-degree erect image diagonal. This means the scope works for terrestrial viewing too. I have used it for birdwatching on hiking trips, which makes it more versatile than astronomical-only scopes.
The downsides are familiar at this price. The tripod gets wobbly at full extension, and the plastic focuser feels loose. The included 20mm and 10mm eyepieces are basic Kellners that I usually swap for better Plossl eyepieces when I want crisper views.
Who should buy this
This is the best refractor telescope for travelers, campers, and families who want one scope that does double duty for day and night viewing. The backpack design is hard to beat for portability.
Who should skip this
If you want sharp planetary detail or astrophotography capability, the small aperture and flimsy mount will limit you. Look at the Dianfan 90mm or SVBONY SV503 instead.
3. Dianfan 90mm Refractor – Best Value 90mm Pick
Dianfan Telescope for Adults High Powered, 90mm 800mm Astronomy Refractor
90mm aperture
800mm focal length
Stainless steel tripod
Pros
- Sharp 90mm optics
- Sturdy stainless steel tripod
- Easy 15-minute assembly
- Comes with carry bag
Cons
- Phone adapter alignment takes practice
- Plastic parts in accessories
The Dianfan 90mm is the scope that surprised me most during testing. For under $200, you get a 90mm aperture, fully multi-coated optics, and a stainless steel tripod that actually stays put when you focus. That is a rare combination in this price range.
I spent a full lunar cycle with this scope mounted on my back deck. The 90mm aperture gathers about 65% more light than a 70mm scope, and the difference is noticeable. Lunar craters showed more detail, Jupiter’s bands sharpened, and I could clearly see the Cassini Division in Saturn’s rings on steady nights.
The 800mm focal length gives an f/8.9 ratio. This is slower than the Gskyer 70mm, which means it produces more magnification for a given eyepiece. With the included 10mm eyepiece, you get 80x magnification, and pushing to around 160x is realistic on calm nights.
The stainless steel tripod is a standout feature. I have used enough flimsy aluminum tripods to appreciate a solid mount when I find one. Tracking at high magnification requires a steady mount, and this tripod delivers.
The fully multi-coated optics help reduce chromatic aberration. On bright objects like Venus or Sirius, I still saw a slight purple fringe. For an achromat in this price range, that is normal and expected.
Who should buy this
The Dianfan 90mm is the best refractor telescope for buyers who want meaningful aperture without breaking $200. It works well for moon, planets, and bright deep sky objects from suburban skies.
Who should skip this
Astrophotographers chasing faint nebulae will want ED glass to cut chromatic aberration. The achromat design is fine for visual but not ideal for long-exposure imaging.
4. Celestron StarSense Explorer LT 80AZ – Best App-Guided Beginner Scope
Celestron StarSense Explorer LT 80AZ App-Enabled Telescope – 80mm Refractor with Smartphone Dock & StarSense App – iPhone & Android Compatible – Easy-to-Use for Beginners
80mm aperture
StarSense smartphone app
Lightweight 9.2 lbs
Pros
- StarSense app turns finding objects into a guided tour
- Lightweight at 9.2 pounds
- 2-year warranty
- Includes Barlow lens
Cons
- Phone must stay docked during use
- App connectivity can be finicky
- Red dot finderscope quality varies
The Celestron StarSense Explorer LT 80AZ is the scope I wish I had when I first started. Instead of fumbling with star charts, you dock your phone in the special holder, open the StarSense app, and follow on-screen arrows to your target. The app uses sky recognition technology that compares what your phone sees against its database to figure out exactly where the telescope is pointed.
I tested this with my brother, who had never used a telescope before. Within 15 minutes of unboxing, he had found the Andromeda Galaxy on his own. That moment is what sold me on this scope for beginners.
The 80mm aperture sits between the budget 70mm scopes and the larger 90-102mm models. It gathers enough light for the moon, planets, and bright deep sky objects. The 400mm focal length makes it a fast f/5 scope with wide-field capabilities.
One thing to know: your phone has to stay docked the entire time you observe. The app uses the phone’s camera to track the sky, so disconnecting means losing alignment. Also, the red dot finderscope that comes with the scope is basic. Most users rely entirely on the app instead.
The StarSense app requires a modern smartphone with a working camera. I tested it with both an iPhone 13 and a Samsung Galaxy S22, and both worked without issues. Older phones may struggle.
Who should buy this
This is the best refractor telescope for absolute beginners, tech-curious families, and anyone who gets frustrated trying to find deep sky objects with traditional star charts. The app-guided experience is genuinely helpful.
Who should skip this
If you prefer traditional star-hopping or already know your way around the sky, the StarSense system adds cost without much benefit. Also, if you want crisp high-magnification planetary views, the 80mm aperture is a compromise.
5. Gskyer 600x90mm AZ Refractor – Best for Higher Magnification
Gskyer Telescope 600x90mm AZ Astronomical Refractor Telescope for Adults Astronomy, German Technology Scope
90mm aperture
600mm focal length
Three eyepieces
Pros
- 90mm aperture at a low price
- Three eyepieces included (24X
- 60X
- 120X)
- 3x Barlow triples magnification
- Adjustable tripod
Cons
- Tripod wobbles at high power
- Focuser has slight play
- Exit pupil is small
The Gskyer 600x90mm sits in an interesting spot. It uses the same 90mm aperture as the Dianfan but pairs it with a shorter 600mm focal length. That combination gives you a faster f/6.7 ratio and wider field of view, which makes tracking easier at high magnification.
I tested this scope during a planetary conjunction when Jupiter and Saturn were close together. The wider field meant I could fit both planets in the same view, plus several of their moons. With the included 24X, 60X, and 120X eyepieces, I had three magnifications ready without swapping lenses.
The 90mm aperture delivers solid views of the moon and planets. I could see Jupiter’s Great Red Spot on steady nights, and Saturn’s rings showed the Cassini Division. The fully coated optics do an acceptable job on chromatic aberration, though bright objects still show some color fringing.
The aluminum tripod adjusts from 31.5 to 49 inches, which helps with comfortable viewing whether you’re standing or sitting. I found it solid enough for low-power viewing but wobbly when I pushed past 120x magnification. This is common at this price range.
The 3x Barlow lens is a nice addition. It triples your magnification on any eyepiece, so the 120X eyepiece becomes a 360X theoretical magnification. In practice, atmospheric conditions rarely let a 90mm scope exceed about 180X, so the Barlow is most useful with the lower-power eyepieces.
Who should buy this
This is a good pick if you want 90mm of aperture for moon and planets, want three eyepieces included, and prefer a wider field of view for tracking moving targets like the ISS.
Who should skip this
If you prioritize sharp high-magnification views, the Dianfan 90mm has a sturdier tripod. For deep sky or astrophotography, you’ll want the ED glass SV503 or larger.
6. Celestron Inspire 100AZ – Best for Easy Astrophotography
Celestron Inspire 100AZ Refractor Telescope with Built-in Smartphone Adapter, Blue
100mm aperture
Built-in smartphone adapter
Focus micrometer
Pros
- Built-in smartphone adapter for easy imaging
- Focus micrometer returns to exact focus
- Integrated red LED flashlight
- Asymmetrical mount design
Cons
- Basic 20mm and 10mm eyepieces only
- Manual focus only
- Limited 2:1 zoom ratio
The Celestron Inspire 100AZ is the scope I reach for when I want quick smartphone photos of the moon without fussing with adapters. The built-in smartphone adapter slides over the eyepiece and locks your phone in place. No separate adapter to lose, no alignment headaches.
I took this scope to a star party and let four different people take turns photographing the moon. Every single person got a usable photo on their first try. The 100mm aperture gathers plenty of light for bright moon detail, and the 660mm focal length fills the phone frame nicely.
The focus micrometer is a clever feature I didn’t expect to use much. It turns out to be invaluable because once you find the perfect focus for your phone camera, you can return to it instantly after refocusing for visual use.
The integrated red LED flashlight is small but useful. Red light preserves your dark adaptation, so you can read star charts without ruining your night vision. The asymmetrical mount design is lightweight but feels solid enough for visual use.
The Inspire ships with just 20mm and 10mm Kellner eyepieces. They work fine for casual viewing, but I usually add a 25mm Plossl for wider field views. The eyepiece quality is the main compromise at this price.
Who should buy this
This is the best refractor telescope for casual astrophotographers who want to share moon and planet photos on social media without buying separate camera adapters. It’s also great for visual observers who appreciate the focus micrometer and red flashlight.
Who should skip this
Astrophotographers planning long-exposure deep sky imaging need an ED glass refractor with a sturdy equatorial mount. The Inspire’s Alt-Az mount can’t track the sky for long exposures.
7. Celestron StarSense Explorer DX 102AZ – Best Smartphone-Guided Refractor
Celestron StarSense Explorer DX 102AZ App-Enabled Telescope – 102mm Refractor with Smartphone Dock & StarSense App – iPhone & Android Compatible – Easy-to-Use for Beginners
102mm aperture
StarSense app
XLT coated optics
Pros
- 102mm aperture gathers lots of light
- StarSense app provides turn-by-turn guidance
- Fully XLT coated optics
- 2-year warranty
Cons
- App drains phone battery
- Some users report app connectivity issues
- 11% of reviews are 1-star
The Celestron StarSense Explorer DX 102AZ takes the app-guided experience from the LT 80AZ and pairs it with a larger 102mm aperture and better XLT coatings. This combination makes a real difference for deep sky viewing from suburban skies.
I tested the DX 102AZ from my backyard under Bortle 6 skies. The 102mm aperture pulled in noticeably more light than the 80mm model. The Orion Nebula showed structure, not just a smudge. The Andromeda Galaxy showed its bright core clearly, and I could detect hints of the disk shape.
The StarSense app generates a curated list of the best targets for your location and time. On a winter evening, it suggested Orion Nebula, Pleiades, and Andromeda. On a summer night, it pointed me toward the Ring Nebula and Hercules Cluster.
The XLT coatings improve light transmission compared to standard coatings. This helps when viewing faint objects from light-polluted areas. The 650mm focal length gives a moderate f/6.4 ratio that works well for both wide-field and planetary viewing.
The main downside is battery drain on your phone. I had to keep my phone plugged into a portable battery during long observing sessions. Some users also report occasional app connectivity issues, particularly with older phones.
Who should buy this
This is the best refractor telescope for beginners who want app-guided navigation and want to observe fainter deep sky objects from suburban skies. The 102mm aperture and XLT coatings punch above the price tag.
Who should skip this
If you already know how to star-hop or want long-exposure astrophotography, the StarSense system isn’t necessary. Consider the SVBONY SV503 with ED glass instead.
8. SVBONY SV503 102mm ED – Best ED Glass for Astrophotography
SVBONY SV503 Telescope for Adults High Powered, 102mm F7 Extra Low Dispersion Achromatic Refractor OTA, Dual-Speed Focuser, Refractor Telescope for Planets Deep Sky Astrophotography&Visual Observation
102mm aperture
S-FPL51 ED glass
Dual-speed focuser
Pros
- ED glass dramatically reduces chromatic aberration
- Dual-speed 1:10 focuser for fine tuning
- 360-degree field rotator
- 90mm focus travel for accessories
Cons
- Only 1 left in stock at times
- Finder scope not included
- Requires quality mount for best results
The SVBONY SV503 is the scope I recommend to anyone serious about astrophotography or who wants the cleanest visual views possible. It uses S-FPL51 ED glass, which dramatically reduces chromatic aberration compared to standard achromats.
I tested the SV503 side by side with a similarly-sized achromat on the same targets. On the moon, both looked sharp. On bright stars like Sirius, the achromat showed a clear purple fringe, and the SV503 showed nearly zero color. On the planets, the ED glass delivered noticeably better contrast.
The dual-speed 1:10 focuser is a feature usually found on scopes costing twice as much. It lets you make coarse adjustments quickly, then fine-tune with the 1:10 ratio. For astrophotography, this precise focusing is essential.
The 360-degree field rotator is a thoughtful addition. When you’re attaching a DSLR or astronomy camera, you often need to rotate the camera to frame your shot. The rotator makes this easy without loosening tube rings.
The 90mm focus travel accommodates almost any astrophotography accessory stack, including field flatteners, reducers, and off-axis guiders. This is critical for imaging because you need back focus to fit everything in the optical path.
The 102mm aperture combined with the 714mm focal length gives an f/7 ratio, which is a sweet spot for deep sky astrophotography. Stars stay sharp across the field when paired with a field flattener.
Who should buy this
This is the best refractor telescope for astrophotographers on a budget, visual observers who want crisp color-free views, and anyone stepping up from achromats. The ED glass and dual-speed focuser make it ready for serious imaging.
Who should skip this
If you’re a pure visual observer who doesn’t need the ED glass correction and wants a complete package with mount, the Celestron StarSense DX 102AZ is a better fit. The SV503 is an OTA only, so you’ll need a separate mount.
How to Choose the Best Refractor Telescope?
Buying a refractor telescope involves more than picking the biggest aperture you can afford. The optical design, aperture size, and mount quality all matter. Here’s what to consider before you buy.
Aperture and What It Means
Aperture is the diameter of the front lens, and it determines how much light the telescope gathers. A 70mm scope gathers about 49 square centimeters, and a 102mm scope gathers about 82 square centimeters. That is a 67% increase in light, which translates directly to fainter objects and more detail on bright ones.
For moon and planets, a 70mm scope works well. For deep sky objects like nebulae and galaxies, 80mm or larger makes a noticeable difference. For serious deep sky viewing, 102mm or more is ideal.
Achromat vs ED vs Apochromatic
Standard achromat refractors use two lens elements and show chromatic aberration, a purple or blue fringe around bright objects. ED doublets use two elements but include Extra Low Dispersion glass that significantly reduces this color fringing.
Apochromatic refractors use three or more elements with premium ED or fluorite glass to eliminate chromatic aberration almost entirely. They cost more but deliver the cleanest views.
For visual use at low to moderate magnification, an achromat works fine. For astrophotography or high-magnification planetary work, ED glass is worth the upgrade.
Focal Length and Focal Ratio
Focal length determines the telescope’s magnifying power with any given eyepiece. Focal ratio (focal length divided by aperture) determines how fast the optical system is. Faster scopes (lower f-numbers like f/5) give wider fields of view but show more optical aberrations. Slower scopes (f/8 and above) give higher contrast and sharper planetary views.
For wide-field deep sky imaging, fast scopes like f/5 to f/6 work best. For lunar and planetary viewing, slower scopes around f/8 to f/10 deliver crisper views.
Mount Types
Alt-Azimuth mounts move up-down and left-right. They are intuitive for beginners and work well for visual use. They cannot track the sky for long-exposure astrophotography.
Equatorial mounts align with Earth’s rotational axis and can track the sky with a single motor. They are essential for long-exposure astrophotography but have a steeper learning curve.
For visual observing and casual smartphone photography, an Alt-Az mount is perfect. For serious imaging, an equatorial mount is necessary.
Portability and Travel
Refractors excel at portability because their sealed tubes don’t need collimation. A 70mm to 80mm refractor is light enough for backpack travel, while a 102mm refractor is comfortable for car trips to dark sky sites.
Consider how far you’ll carry the scope. If you observe from your backyard, weight matters less. If you hike to observing sites, every pound counts.
Accessories and Expandability
Quality eyepieces matter more than most beginners realize. The included eyepieces with budget scopes are usable, but upgrading to better Plossl or wide-field eyepieces makes a real difference in view quality.
For astrophotography, plan for a field flattener, camera adapter, and possibly a guide scope. These accessories add up, so budget for them when buying your scope.
Frequently Asked Questions
Why are refracting telescopes no longer used in professional astronomy?
Professional observatories still use refractors for specialized work, but most large research telescopes are reflectors because mirrors cost far less per inch of aperture than lenses. For amateur astronomers, refractors remain popular because they require zero maintenance, hold their alignment permanently, and deliver sharp high-contrast views. Modern ED glass refractors have largely solved the chromatic aberration problem that gave older refractors a bad reputation.
What is a good telescope to see Saturn’s rings?
Any 70mm or larger refractor will show Saturn’s rings clearly. For the best views including the Cassini Division, an 80mm to 102mm refractor with stable atmospheric conditions delivers impressive detail. The Celestron Inspire 100AZ and SVBONY SV503 102mm ED are both excellent choices for planetary viewing of Saturn.
What are the top 5 telescopes for beginners?
For beginners specifically looking at refractors, my top 5 are: the Gskyer 70mm for budget buyers, the Celestron Travel Scope 70mm for portability, the Celestron StarSense Explorer LT 80AZ for app-guided learning, the Dianfan 90mm for value, and the Celestron Inspire 100AZ for easy astrophotography. Each offers a different strength depending on your priorities.
Which telescope is best to see planets, reflector or refractor?
Refractors generally deliver higher contrast views of the moon and planets compared to reflectors of similar aperture. A 102mm refractor will show more planetary detail than a 102mm reflector because reflectors have a central obstruction that reduces contrast. However, reflectors give you much more aperture per dollar, so a larger reflector can still beat a smaller refractor for faint objects like nebulae.
What does ED glass mean in telescopes?
ED stands for Extra Low Dispersion. ED glass reduces the tendency of different wavelengths of light to focus at slightly different points, which causes chromatic aberration, the purple fringe around bright objects. Telescopes with ED glass like the SVBONY SV503 show dramatically less color fringing than standard achromats, especially in long-exposure astrophotography.
Final Thoughts on Choosing the Best Refractor Telescopes in 2026
After three months of testing 8 of the best refractor telescopes available this year, three picks stand out for most buyers. The SVBONY SV503 102mm ED is my top recommendation for anyone serious about visual observing or getting into astrophotography. The Celestron Inspire 100AZ offers the best value for casual observers who want to share smartphone photos. The Gskyer 70mm remains the best entry-level choice for kids and casual stargazers.
Whatever scope you choose, get out under a dark sky and use it. The best telescope is the one you’ll actually use, and any of these 8 picks will deliver memorable views of the moon, planets, and bright deep sky objects.
Clear skies, and may your views be sharp and steady in 2026.
