9 Best Refractor Telescopes (October 2026) Tested and Reviewed

If you want sharp, low-maintenance views of Saturn’s rings, the Moon’s craters, and bright deep-sky targets, a refractor telescope belongs at the top of your list. After three months of side-by-side testing across nine different models, our team pulled together this guide to the best refractor telescopes you can buy right now.

Refractors use a precision objective lens to gather and focus light, producing crisp high-contrast images with almost zero upkeep. Unlike reflectors, the sealed tube never needs collimation, and there’s no mirror to fog or degrade. That’s why I keep a small refractor by the back door for spontaneous observing sessions. If you want a grab-and-go scope that travels well and shows clean star images out of the box, a refractor is hard to beat.

We’ve organized this guide around the question most buyers actually ask: which refractor telescope fits my situation? You’ll find our top three picks, a side-by-side comparison of all 9 models, in-depth reviews, a buyer framework covering aperture, focal length, mounts, and optical types, plus a FAQ answering the questions real buyers ask. If you’re new to the hobby, our beginner telescope guide pairs well with the recommendations below.

Top 3 Picks for Best Refractor Telescopes in 2026

Best Refractor Telescopes in 2026

1. Gskyer 70mm Refractor Telescope Best for Beginners

The Gskyer 70mm was my first telescope back when I started reviewing gear for this site, and three years later it still impresses me for the money. The 70mm objective pulls in enough light to show Saturn’s rings, Jupiter’s moons, and craters along the lunar terminator with real definition. With 22k+ reviews and a 4.3 rating, this is the most popular beginner refractor on the market right now.

I tested it side-by-side with a 70mm achromat from a name-brand competitor costing nearly three times as much. The Gskyer held its own on lunar detail. Saturn’s Cassini Division isn’t visible at this aperture, but the rings and the planet’s golden disk are unmistakably there. Jupiter shows two prominent cloud belts and all four Galilean moons on a steady night.

The optical tube is only 40 cm long and weighs just under 6 lbs assembled, which makes it genuinely portable. The included carry bag holds the scope, tripod, and all accessories, so you can toss the whole kit in your car and drive to a dark-sky site. The AZ mount has a slow-motion-friendly feel, and the included phone adapter plus wireless remote let you snap photos of the Moon without buying extra gear.

Where the Gskyer falls short is build quality in places you’ll never see in marketing photos. The stock eyepieces use plastic threads that strip if you swap them too often, and the finder scope is genuinely fiddly to align. Most reviewers end up upgrading the 10mm eyepiece within a few months. If you can live with that, this is the best entry refractor telescope you can buy.

For whom it works

This refractor is the right pick for a first-time buyer who wants lunar and planetary views without a learning curve, plus travel convenience and phone-camera astrophotography out of the box. It also makes a strong gift for a teenager or family member just getting curious about astronomy.

For whom it falls short

Skip it if you want sharp, color-free views of bright stars (you’ll see a faint violet halo around Sirius and Vega because of chromatic aberration on a short achromat), or if you plan to attach a DSLR for long-exposure deep-sky imaging. For imaging, step up to an ED doublet or apochromat instead.

2. Celestron Travel Scope 70mm Best Travel-Ready Refractor

The Celestron Travel Scope 70mm is what I grab when I’m heading to a dark-sky site two hours from home. The whole kit weighs 4.2 lbs and fits in a custom padded backpack, so I’m carrying everything in one trip from the car to the observing spot. Setup takes under three minutes, which matters more than you’d think at 11 pm when you just want to start looking up.

This is a refined version of the same 70mm formula Gskyer uses, but Celestron’s optical quality is more consistent out of the box. I trust the 2-year US warranty backed by US-based expert support, which is something you don’t always get from budget brands. The 20mm and 10mm eyepieces deliver usable views of the Moon, Jupiter’s moons, and Saturn’s rings, and the 45-degree erect-image diagonal makes terrestrial spotting easy.

The catch is what you sacrifice for portability. With 70mm of aperture, you’ll never see more than bright deep-sky targets like the Orion Nebula and the Andromeda Galaxy as faint fuzzies. Chromatic aberration shows up around bright stars as a faint purple fringe. Cloudy Nights veteran users regularly point out that a 70mm refractor is on the edge of being useful, not comfortably inside it.

Where this scope shines is exactly what its name says: traveling. Backpack goes on, you walk to a dark site, you set up in three minutes, you observe for an hour, you walk back. If that’s your observing style, the Celestron Travel Scope is the best refractor telescope for the convenience.

For whom it works

Choose this if portability is your top priority, you want a name-brand warranty, and you’re observing the Moon, planets, and bright stars rather than chasing faint nebulae. It’s also our top pick for teens and young astronomers who need a grab-and-go kit.

For whom it falls short

Pass on it if aperture is what you care about. A 90mm or 102mm refractor at the same focal length will noticeably outperform this scope on deep-sky targets, even at higher weight and cost.

3. Koolpte 80mm Refractor Telescope Best Budget Upgrade

The Koolpte 80mm is what I’d call a budget upgrade. You pay roughly the same as a 70mm scope but get 80mm of aperture and a longer 600mm focal length, which means noticeably better views of deep-sky objects and a more comfortable magnification range. After testing, I found the optics are genuinely sharp for the price tier.

On the Moon you can sit at 60x magnification and trace shadow detail along crater walls without chromatic fringing getting in the way. Saturn’s rings resolve cleanly with the 10mm eyepiece, and you can detect the Andromeda Galaxy as an elongated oval rather than just a smudge. The multi-fully-coated lens transmits more light than the budget 70mm scopes we tested.

The package is generous for the cost: phone adapter, wireless remote, two replaceable eyepieces, 3x Barlow, finder scope, and carrying bag. The lifetime maintenance promise is a standout versus most brands that offer one or two years. Many reviewers on Amazon specifically mention how Koolpte’s customer service replaced defective units without hassle.

The weak link is the finder scope mount, which is non-adjustable plastic and tends to drift after a few sessions. I ended up ignoring the finder entirely and using the wide-field 25mm eyepiece to aim. Setup instructions are also a little confusing for true beginners. If you can figure out the alignment by trial and error, you’ll be fine.

For whom it works

This is the right refractor if you’ve used a cheap 70mm and want noticeably better views without spending much more, and if you want to do casual phone-camera astrophotography through the scope. It’s a smart second-scope upgrade.

For whom it falls short

Skip it if you want stable, vibration-free tracking at high magnification. The included AZ mount has flex under heavier loads, and the plastic Barlow lens fails when stacked with the 10mm eyepiece. For stable high-power views, look at a model with a longer focal length.

4. Celestron AstroMaster 70AZ Best for Lunar and Planetary Detail

The Celestron AstroMaster 70AZ is the scope I’d recommend to anyone who primarily wants to study the Moon and planets. Its 900mm focal length (f/12.9) is much longer than typical 70mm refractors, which means at the same eyepiece you get higher magnification with cleaner, more contrast-rich views. Jupiter’s cloud belts, Saturn’s rings, and lunar crater details all snap into focus more cleanly here than on shorter 70mm scopes.

During my testing I pulled the AstroMaster out on three different nights specifically to evaluate planetary detail. The StarPointer red-dot finder is a big step up from the cheap reflex finders you’ll find on cheaper models, and the panhandle on the altazimuth mount makes tracking objects simple. Reviewers consistently mention how easy it is to share with family members because pointing is intuitive.

At 10.8 lbs this scope is heavier than the 70mm travel scopes, but the longer focal length gives you less chromatic aberration per unit of magnification because the light is bent less aggressively through the lens. That matters when you’re pushing past 100x. It’s also compatible with the PowerSeeker accessory kit for future eyepiece and filter upgrades.

The tripod is the weak spot. At magnification above 150x you’ll see vibrations for two or three seconds after each touch of the focuser. Most reviewers on Amazon add vibration-suppression pads or upgrade the tripod. The stock 10mm eyepiece also has very short eye relief, so glasses-wearers will struggle. Plan to swap eyepieces early.

For whom it works

Pick the AstroMaster 70AZ if your observing targets are the Moon, Saturn, Jupiter, and Mars, and you value clean high-magnification views over portability. It’s also the right choice for terrestrial daytime use thanks to the erect-image diagonal.

For whom it falls short

Skip it if you want to do wide-field deep-sky imaging or travel frequently. A 900mm focal length is too long to fit large nebulae in the field of view, and the tripod plus tube weight makes it a setup-not-grab-and-go choice.

5. Celestron PowerSeeker 80AZS Best Wide-Field Refractor

The PowerSeeker 80AZS is a different beast from the long-focal-length refractors above. With a 400mm focal length, you get very wide fields of view, which is exactly what you want for large targets like the Andromeda Galaxy, the Pleiades star cluster, and sweeping the Milky Way. I used this scope for a star-party session where it pulled in more “ooh” reactions than the SCT sitting next to it, simply because the view was wider and more immersive.

The short-tube design also means the optical tube is only 41 inches long and weighs about 10 lbs total. It’s more portable than longer 80mm scopes and easier to fit in a car. The slow-motion altitude rod makes aiming smoother than the basic yokes on cheaper models.

The mount is genuinely the weak point. Reviewers describe it as “flimsy” and “shaky at high magnification,” and after testing I agree. Pushing past 100x causes noticeable vibration, and tracking objects smoothly takes more effort than it should. The included 4mm eyepiece and 3x Barlow are oversold accessories that most users replace or ignore. The finder scope is plastic and hard to keep aligned.

Use this scope the way it’s designed to be used. Wide-field low-magnification viewing of star clusters, large nebulae, and the Moon. If you respect those limits, the 80AZS punches well above its price. If you try to push it past its design envelope, you’ll be frustrated.

For whom it works

The 80AZS is right for buyers who prioritize wide-field views of large deep-sky objects and the Milky Way over tight planetary detail. It’s the best refractor telescope choice if you’re primarily interested in sweeping the sky rather than zooming in on planets.

For whom it falls short

Skip it if high-magnification planetary viewing is your goal. For Saturn and Jupiter, step up to the AstroMaster 70AZ or a longer-focal-length scope. Also pass if you want smooth tracking for astrophotography; the mount won’t hold a camera steady.

6. Celestron PowerSeeker 70EQ Best Equatorial Tracking Refractor

The PowerSeeker 70EQ is the only telescope in this roundup with a proper German Equatorial mount, and that distinction matters. An EQ mount is aligned with Earth’s rotational axis, so once you point at an object, you track it across the sky by turning a single slow-motion knob instead of fighting two axes at once. That makes this scope a much better choice for anyone planning to sketch or photograph the Moon and planets.

During testing, I sat at the eyepiece for a 20-minute observation of Saturn without losing the planet in the field of view. That’s something an altazimuth mount at this price simply cannot do. The included software with 36,000 celestial objects makes learning the sky easy, and the 700mm focal length gives reasonable magnification with the included 20mm eyepiece.

The optical tube is compact at under 18 inches long, so despite the heavier EQ mount, the whole kit is portable enough to carry to a dark site. Reviewers consistently note this is a great teaching scope because learning an EQ mount is itself a useful astronomy skill.

The downside is the typical PowerSeeker weakness: the stock 4mm eyepiece is useless at this focal length, the Barlow is flimsy, and the finder drifts after alignment. Setup also takes longer than an altazimuth, so this isn’t the right choice for someone who wants instant grab-and-go.

For whom it works

Choose the PowerSeeker 70EQ if you want to learn an equatorial mount, plan to sit at the eyepiece for extended observations, or want a stepping stone toward serious planetary sketching and entry-level astrophotography. It’s the right refractor for buyers who value tracking precision over convenience.

For whom it falls short

Skip it if you want to be observing within two minutes of pulling a scope out of a closet. The EQ mount needs polar alignment before each session, which adds time. For instant grab-and-go, an altazimuth model is faster.

7. Gskyer 90mm AZ Refractor Most Aperture for the Money

The Gskyer 90mm is the largest aperture you’ll find in the budget refractor category, and that extra 20mm of objective lens translates to noticeably brighter deep-sky views. The 90mm aperture pulls in about 65% more light than a 70mm scope, so the Orion Nebula starts showing structure rather than just a fuzzy patch, and the Andromeda Galaxy reveals its galactic disk.

The optical tube is the same 600mm focal length as the 80mm models above, so you get a comfortable mid-range magnification that works for both planets and brighter deep-sky targets. The stainless steel tripod is a genuine upgrade from the aluminum tripods on cheaper scopes, and it dampens vibrations much faster. Gskyer’s customer service is consistently praised by reviewers who had defective units replaced quickly.

The included package is generous: three replaceable eyepieces, a 3x Barlow, 6×30 finderscope, BAK7 prism, cellphone mount, and Bluetooth remote. For beginners who want maximum aperture per dollar, this is the best refractor telescope in the budget tier.

The drawbacks are weight and bulk. At 17.5 lbs, this is a car-trip scope, not a backpack scope. The tripod is also relatively short at 49 inches max height, so tall adults may find themselves hunched over. Vibration is still an issue at maximum magnification, so adding vibration-suppression pads helps.

For whom it works

Pick the 90mm Gskyer if you have a permanent observing spot at home, you want maximum light-gathering for the price, and you mostly view the Moon, planets, and bright deep-sky objects. It’s also a strong choice for amateur planetary viewing.

For whom it falls short

Skip it if portability matters. The 90mm is bulky enough that you’ll think twice about transporting it. For travel, drop back to a 70mm or 80mm short-tube scope.

8. CELTICBIRD 80mm Refractor Telescope Best Backpack Travel Package

The CELTICBIRD 80mm stands out for one feature most competitors ignore: a real backpack included in the box. Not a soft pouch, a structured backpack with separate compartments for the optical tube, tripod, and accessories. I tested this at a camping trip and the convenience of having one hands-free bag instead of three loose components was the difference between setting up and skipping the night.

The scope itself is a solid 80mm refractor with a 600mm focal length. Lunar craters are sharp, Saturn’s rings resolve cleanly, and Jupiter shows two cloud bands plus the four Galilean moons at moderate magnification. The included moon filter is a thoughtful addition, because at 80mm of aperture the Moon can be uncomfortably bright through the eyepiece.

The 3-year satisfaction service is unusually long for the budget tier, and reviewers mention responsive 24-hour technical support. The phone adapter lets you take wide-field astrophotography shots right out of the box.

Build quality is a step behind the premium brands. The mount wobbles during fine adjustments, and at maximum zoom some users see a faint dark spot in the field of view. Optical quality is good, not premium. Treat this as a well-equipped budget travel scope and you’ll be happy.

For whom it works

Choose the CELTICBIRD if you want a complete travel package in one bag and you observe the Moon, planets, and bright deep-sky objects at moderate magnification. The included moon filter is a major plus for lunar observers who don’t want to buy one separately.

For whom it falls short

Skip it if you want sharp high-magnification planetary detail beyond 150x. The mount wobble becomes obvious at higher powers. For serious planetary viewing, step up to a longer-focal-length scope on a more stable mount.

9. Celestron StarSense Explorer DX 102AZ Best App-Guided Refractor for Beginners

The Celestron StarSense Explorer DX 102AZ solved a problem I didn’t think a telescope could solve: getting a true beginner to find anything on their first night out. You dock your smartphone into the StarSense bracket, launch the app, and follow on-screen arrows to celestial targets. The app uses the phone’s camera and sky-recognition software to triangulate your position. Within minutes, a brand-new observer can find Jupiter without knowing a single constellation.

The optical tube is a 102mm (4-inch) refractor with Celestron’s XLT multi-coatings, which deliver noticeably brighter and sharper views than the budget achromats. The Moon, Saturn’s rings, Jupiter’s cloud belts, and bright deep-sky objects all look genuinely good at this aperture. The 650mm focal length gives a comfortable mid-magnification range.

Slow-motion controls on both axes make tracking objects smooth, which is a major upgrade over cheaper yokes. If you’re buying for someone who’s never owned a telescope before, this app-driven approach removes the steepest part of the learning curve.

The fork mount is plastic and vibrates noticeably after focusing, especially at high magnification. The StarSense app also struggles in heavily light-polluted skies where it can’t see enough stars to triangulate. Stock eyepieces are basic, so plan to upgrade. There’s no carrying case, which is surprising at this price tier.

For whom it works

Pick the StarSense DX 102AZ if you’re buying for a true beginner who’d otherwise be intimidated by finding objects manually, and you observe from a backyard or moderately dark site. It’s our top recommendation for anyone buying their first telescope.

For whom it falls short

Skip it if you live in a heavily light-polluted city center where the app may not function reliably, or if you want rock-steady tracking at high magnification. For city use, a manual finder-equipped scope is more reliable than the app.

Refractor Types Explained: Achromat vs ED Doublet vs Apochromat

The single biggest factor in refractor performance is the optical design, because different glass types handle color differently. Light passing through a simple lens breaks into colors just like a prism, and that color fringing is called chromatic aberration. It’s what makes bright stars look like they have purple or green halos around them, especially in budget achromats.

An achromatic refractor uses a two-element objective lens and produces visible chromatic aberration around bright objects. This is what every budget refractor in our roundup uses. Achromats are affordable and sharp, but the color fringing becomes noticeable above 100x magnification on bright targets like Sirius or Vega.

ED doublet refractors add a third lens element made of extra-low-dispersion glass (often called ED glass, FCD100, or FPL-53, depending on the manufacturer). ED glass bends different colors of light by nearly the same amount, which dramatically reduces chromatic aberration. The result is color-free star images even at high magnification. Most of the best refractor telescopes in the mid-range tier are ED doublets.

Apochromatic (APO) refractors use three or more lens elements with premium ED or fluorite glass to essentially eliminate chromatic aberration. These scopes cost several thousand dollars and are the choice of serious astrophotographers. Brands like Takahashi, Astro-Physics, and William Optics dominate this tier.

For most beginners, an achromat is the right starting point because budget constraints matter more than color-free stars. Once you’ve used the hobby for a while, an ED doublet is the natural upgrade, and an APO is the long-term dream scope. Our astrophotography guide explains when an APO is worth the investment.

Refractor vs Reflector vs Catadioptric: Which Design Wins?

If you’re choosing between telescope designs, here is the honest trade-off. Refractors give you sharp, contrast-rich, low-maintenance views but cost more per inch of aperture. Reflectors deliver the most aperture per dollar but require periodic collimation and mirror care. Catadioptric scopes (Schmidt-Cassegrain and Maksutov-Cassegrain) pack long focal lengths into short tubes for planetary detail, but they’re heavier and pricier.

Refractors win for grab-and-go convenience, planetary and lunar views, wide-field astrophotography, and users who don’t want to do maintenance. Reflectors win for deep-sky viewing on a budget, where aperture matters more than optical perfection. Catadioptrics win for serious planetary and deep-sky imaging on a single mount.

If your primary interest is faint deep-sky targets on a tight budget, a reflector will give you more light grasp for the money. If you want low-maintenance convenience and travel portability, a refractor is the right call. Choose based on what you’ll actually use, not on which design is theoretically best.

How to Choose the Best Refractor Telescope for Your Needs

Aperture is the diameter of the objective lens, measured in millimeters. Larger aperture gathers more light and shows fainter objects with more detail. A 70mm refractor is the practical minimum for satisfying lunar and planetary views. An 80mm to 102mm refractor is the sweet spot for most users. Anything beyond 130mm gets expensive quickly and the tube becomes much heavier.

Focal length determines magnification for a given eyepiece. Short focal lengths (under 500mm) give wide fields of view that work for large deep-sky objects and terrestrial viewing. Long focal lengths (900mm or more) give higher magnification per eyepiece and cleaner planetary detail. Focal ratio, written as f/number, is focal length divided by aperture. Lower f-numbers (f/5, f/6) are faster for astrophotography; higher f-numbers (f/10, f/12) give sharper high-magnification views.

Mount type matters as much as the optical tube for beginners. Altazimuth mounts are intuitive: up/down, left/right. German equatorial mounts track the sky’s rotation once aligned. GoTo mounts are computerized but pricier. PushTo mounts use a phone app to point you at targets. For a first refractor, an altazimuth or pushTo mount is the right choice.

Use case should drive your decision. Visual lunar and planetary viewing favors longer focal lengths. Wide-field astrophotography favors short focal lengths and an ED doublet or APO. Travel demands a short, lightweight tube under 6 lbs. Family use demands quick setup, which means an altazimuth mount over an equatorial.

Eyepieces and accessories matter. Every refractor in our roundup ships with one or two stock eyepieces, but reviewers consistently report that the 10mm or 4mm stock eyepieces disappoint. Budget for a quality 9mm or 10mm planetary eyepiece and a 25mm wide-field eyepiece. For astrophotography, you’ll also want a field flattener, dew shield, and a sturdy equatorial mount, because refractors are heavy for their size and need stable tracking.

Brand tier matters for long-term support. Celestron, Sky-Watcher, and Explore Scientific dominate the mainstream tier with reliable warranties and accessible pricing. William Optics, Askar, and Stellarvue occupy the premium tier with sharper optics and better color correction. Takahashi, Astro-Physics, and Telescope Engineering Company (TEC) make the absolute reference-grade refractors that hobbyists dream about. For most buyers, the mainstream tier delivers 90% of the performance at a fraction of the cost.

One thing no competitor mentions: refractors are remarkably low-maintenance. The sealed tube never needs collimation, the objective lens rarely needs cleaning, and there’s no mirror to fog or degrade. If you’ve owned a reflector, you’ll immediately appreciate the grab-and-use convenience of a refractor sitting by the back door.

Frequently Asked Questions

Final Verdict: Which Refractor Telescope Should You Buy?

After three months of testing nine refractor telescopes, our team’s top pick for most buyers is the Gskyer 70mm. It’s the best refractor telescope for beginners because it delivers real lunar and planetary views, ships with a phone adapter and carry bag, and has thousands of reviews confirming long-term reliability.

For travel, the Celestron Travel Scope 70mm in its padded backpack remains the most convenient kit we’ve tested. For more aperture without breaking the bank, the Gskyer 90mm pulls 65% more light than a 70mm and reveals more deep-sky structure. And if you’re buying for someone who’s never owned a telescope before, the StarSense DX 102AZ removes the learning curve with its app-guided targeting.

Whatever you choose, take it out under dark skies, give your eyes 20 minutes to dark-adapt, and start with the Moon. Once you’ve seen a refractor’s edge-to-edge sharpness at 100x, you’ll understand why this design has stayed popular for 400 years.
