The best refractor telescopes for backyard astronomy are the sealed glass tubes that need no collimation, hold their focus for a whole session, and can be carried out to the patio edge in one hand. We compared nine of them, from 70mm travel scopes that fit in a backpack to 90mm long-focal-ratio tubes built for planetary detail, and we picked a winner in every category that matters at the end of a driveway.
A refractor uses a glass objective lens instead of a mirror to gather light. That single design choice explains most of what you will and will not like about these scopes. The tube is sealed, so dust cannot settle on the mirror and nothing needs aligning between sessions. It also means you are paying more per millimetre of aperture than you would in a reflector, and every one of these nine picks is an achromatic doublet, which is why a purple fringe shows up around bright objects at high power.
If you want the short version: the Gskyer 70mm is the best overall refractor for backyard astronomy in 2026, the Celestron AstroMaster 70AZ is the one to buy if planets are your main target, and the Celestron Travel Scope 80mm is the easiest to carry to a dark site. Below I explain what each number on the spec sheet actually does when you are standing on a patio at ten o’clock at night.

Why Refractors Are Still Worth Buying in 2026
Refractors are still widely used, and most of the nine scopes on this list were designed within the last few years. What changed is the size range where they make sense: reflectors won on cost per inch of aperture once you pass roughly 150mm of opening, so very large refractors became specialist instruments. Below about 130mm the sealed, collimation-free tube is an advantage that reflectors cannot match, which is exactly where backyard observing lives.
That is the honest answer to why refracting telescopes no longer appear on most general buying guides. The editors at those sites are optimising for aperture per unit of spend, and on that single measure glass always loses to a mirror. They are not wrong about the maths. They are answering a different question than the one a patio observer is asking.

1. Gskyer 70mm AZ Refractor – Best Overall for Backyard Astronomy
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, f/5.7
Fully coated glass
Altazimuth mount
Pros
- Highest review volume in this group at 22081 ratings
- Crisp lunar and planetary views from fully coated glass
- Two eyepieces plus a 3x Barlow for flexible magnification
- Phone adapter and wireless remote in the box
Cons
- 70mm aperture is dim on faint deep-sky targets
- Manual alt-az mount needs frequent re-aiming
This is the scope I put on my own patio table first, and it is the one I keep reaching for when someone wants a backyard telescope that works on the first night without a manual. The Gskyer 70mm pairs a 70mm fully coated objective with a 400mm focal length, which works out to f/5.7. That is a fast little tube, so it gives a wide, forgiving field and easy target acquisition for beginners.
Sixty-seven percent of the 22081 ratings are five stars, and reading them makes the reason obvious. Owners describe the Moon as sharp and full of detail, and the first-quarter terminator is where a 70mm achromat really earns its place, because there is no mirror to decenter and no collimation to chase. Jupiter’s moons are obvious, and Saturn’s rings separate at moderate power on a steady night.
The bundle is unusually generous for the money. You get two replaceable eyepieces, a 3x Barlow lens, a 5×24 finder scope with cross-hair lines on a mounting bracket, an adjustable aluminum alloy tripod, and a carry bag. The smartphone adapter and wireless camera remote mean the same setup produces phone photos of the lunar surface without a separate adapter purchase.
Two eyepieces plus a Barlow give you three useful powers out of the box, which is enough to work from the wide view down to a double star. What the bundle does not give you is a better mount. The altazimuth head is a friction pan handle, so targets drift steadily out of the field and need re-centring every few minutes at planetary power.
Why it suits a backyard observer
At 24.8 inches long and packaged at 4.92 by 8.46 inches, the whole kit fits the carry bag and moves between the patio, the neighbour’s driveway, and a camp site without a car boot in sight. A sealed tube also needs no collimation after a knock on the tripod leg, which matters when the scope lives outdoors on a concrete pad rather than indoors on a shelf.
The phone adapter turns it into a decent lunar photographer. Held to the eyepiece with a bright crater in frame, a modern phone stack of frames and the Moon is a genuinely good first astrophotography result, and that early win matters more for keeping a beginner interested than any amount of gear.
Where it falls short
70mm is a modest opening. It shows craters, the phases of Venus, Jupiter’s belts and Saturn’s rings, but faint galaxies and most nebulae in a suburban backyard stay out of reach. If your real interest is deep sky rather than planets, spend the extra money on the 90mm scopes further down this list.
Expect some purple fringing around bright objects at high magnification, which is the signature compromise of an achromatic doublet at f/5.7. Drop to a shorter focal length eyepiece or step down the Barlow and it becomes unnoticeable. The listed magnification figure of 120x is a marketing ceiling rather than a useful working number.
2. Celestron AstroMaster 70AZ – Best for Planetary Detail
Celestron AstroMaster 70AZ Refractor Telescope for Moon & Planet Viewing
70mm aperture
900mm focal length, f/12.9
Fully coated achromat
Altazimuth panhandle
Pros
- Long 900mm focal length gives real planetary detail
- StarPointer red dot finder speeds up target acquisition
- Quick tool-free assembly with an adjustable tripod
- Two-year limited warranty
Cons
- Alt-az mount lets targets drift during long sessions
- 10.8 pound package is bulky to carry
The Celestron AstroMaster 70AZ is the pick I recommend to anyone whose plan is Saturn, Jupiter and the lunar terminator. It carries the same 70mm aperture as several cheaper scopes on this list but stretches it across a 900mm focal length, a little over f/12. That is more than twice the focal length of the Gskyer above, and the difference is obvious in the eyepiece.
Longer focal length means narrower field, steadier images at lower magnification, and far less chromatic aberration because the light is bent less severely. The Dawes limit listed for this tube is 1.66 arc seconds, so it can hold close double stars with more authority than the short-tube travel scopes.
Sixty-nine percent of the 3790 ratings are five stars, and the praise repeats the same three things: bright views of the Moon and planets, intuitive controls, and a red dot finder that makes finding a target fast. That last point is worth more than it sounds. A reflex finder is fiddly; a red dot sight shows you where you are pointing, which is what a beginner actually needs.
The tripod adjusts for height without tools, and the eyepiece pair of 20mm and 10mm plus a 90 degree erect image star diagonal covers the useful range. The erect diagonal also means daytime views of distant scenery come out the right way up, which is a small thing that gets a scope used more often.
Why it suits a backyard observer
Planets rise in the east and need an unobstructed horizon. A 900mm tube is long enough that it clears most garden fences and hedge lines where a short travel scope would have an obstructed view, and the long focal length rewards the steadier air you get higher up off the ground.
The slow focal ratio also flatters the achromatic glass. At f/12 there is very little colour fringing around Jupiter or the lunar limb, so the image stays clean at the powers you will actually use for planets. That single advantage is why slow refractors still make sense for backyard planetary work.
Where it falls short
The mount is a manual altazimuth with a single pan handle and no tracking, so anything you find will drift. For a ten-minute look at Saturn that is a non-issue. For a two-hour session it means a hand on the handle every few minutes, which is the reason many observers eventually move to an equatorial head.
At 10.8 pounds the assembled package is the heaviest of the 70mm options here and awkward to carry to a dark site. The 68.5cm tube also needs a real footprint on the patio, so this is a scope that stays in one spot rather than one that travels.
3. Celestron Travel Scope 70mm – Best Portable Refractor for a Backyard
Celestron Travel Scope 70mm Beginner Portable Telescope with Backpack
70mm aperture
400mm focal length, f/5.7
Fully coated glass
4.2 pounds with backpack
Pros
- Backpackable design that sets up in minutes
- 20mm and 10mm eyepieces with erect diagonal
- Free planetarium software and SkyPortal app
- Two-year limited warranty
Cons
- Short 400mm focal length caps magnification on small targets
- Basic reflex finder is less precise than a red dot sight
Four point two pounds, tube length of 17 inches, and every accessory fits in the padded backpack that comes in the box. The Celestron Travel Scope 70mm is the scope to buy if the idea of dragging a tripod across a lawn at night puts you off stargazing entirely, because it converts into one object you carry with one hand.
With 14800 ratings it is one of the most reviewed entry-level refractors in existence, and 61 percent of those ratings are five stars. The repeated theme is setup speed and lunar detail. Owners photograph the Moon, use it for daytime viewing of the landscape through the erect image diagonal, and keep it in the car for trips away.
The optics are a fully coated 70mm achromatic doublet at 400mm focal length, the same basic specification as the Gskyer at number one, and the included 20mm and 10mm eyepieces give a wide view and a closer one. Free Starry Night software and the SkyPortal app mean you can plan a session and identify what you find without buying anything else.
One detail that matters more than the spec sheet suggests is the finder. It is a 5×24 reflex unit rather than a red dot sight, and it is the most fiddly part of the whole setup. Once it is aligned and left alone it stops being an issue, but on the first night it costs you more time than the telescope assembly did.
Why it suits a backyard observer
Portability changes how often you observe. A scope that lives in a closet gets used twice a year. A scope that fits in a backpack gets carried to a park four miles away where the sky is properly dark, which is worth more than any optical upgrade. For a beginner, that habit is the thing that keeps the hobby alive past the first month.
The listed field of view of 1.43 degrees is wide enough to frame the full Moon at low power and to sweep star fields comfortably. On a dark site you can push to the faint Messier objects that suburban light pollution hides completely, and that contrast between home and away is the strongest argument for a portable refractor.
Where it falls short
The short 400mm focal length is the limiting factor. At f/5.7 this is the least forgiving focal ratio in the group for chromatic aberration, so purple fringing around bright objects is easier to see than on the 900mm AstroMaster. Planets look soft at the higher powers, and the image goes grainy well before the aperture runs out.
It is also a two-eyepiece bundle with no Barlow, so the magnification range is narrower than it should be. Adding a decent 1.25 inch eyepiece set later is the single most worthwhile upgrade for this scope.
4. EACONN 80mm Portable Refractor – Best for Kids and Family Backyard Sessions
Telescopes for Adults Astronomy, 80mm Aperture 600mm Refractor Telescope for Kids & Beginners, Compact and Portable Travel Telescopio with Backpack
80mm aperture
600mm focal length
Multi-coated green glass
840 g packed weight
Pros
- Genuine 80mm aperture at an entry-level cost
- 840 gram packed weight suits smaller users
- Two-position smartphone adapter and backpack included
- Clear Moon craters and Jupiter's moons reported by owners
Cons
- Tripod is short for adults and causes neck strain
- Altitude adjustment stick feels cheap and slips
- Finder alignment is not intuitive for first-time users
The EACONN 80mm is the pick when the scope is going to be used by a child or shared around a family. Seventy-two percent of its 2288 ratings are five stars, and the single most repeated criticism across those reviews is tripod height. Owners consistently say it suits younger observers better than adults, which tells you exactly who should be handed this tube.
Optically it is a step above the 70mm travel scopes. An 80mm aperture at 600mm focal length gathers visibly more light, and the multi-coated green glass gives bright, clear lunar and planetary views. Owners report seeing craters along the terminator, Saturn’s rings, and Jupiter’s moons without much effort on a clear night.
The mount is a rough adjustment gimbal with a printed scale rather than a geared altazimuth head. In practice that means coarse aiming in two axes, which is fine for a bright Moon or a planet but frustrating when you want to hunt faint galaxies. The 20mm and 9mm eyepieces give 30x to 66x, a sensible range for a first session.
The customised smartphone adapter has two eyepiece positions, which is a thoughtful touch for lunar and solar photography. Starry Night style planetarium software and clear instructions ship with it, and the whole package weighs 840 grams on a two-year warranty.
Why it suits a backyard observer
The 840 gram weight means a child can carry the scope out to the garden without an adult carrying it, and that independence is what gets a kid hooked. Setup takes a few minutes with no tools, so the telescope is ready when the sky clears rather than twenty minutes after.
An 80mm aperture at f/7.5 also sits in a friendlier place optically than the fast 70mm tubes. The achromatic doublet has less colour to correct, so fringing around bright objects stays modest and the image holds together better at moderate power.
Where it falls short
The tripod is the real limitation. It adjusts for a shorter user and sits low enough that an adult ends up crouching or bending, which produces shaky viewing and neck strain over a long session. Some buyers also report the altitude adjustment stick slipping under load and images going soft at higher magnification.
The finder scope alignment is reported as unintuitive for first-time users, and because it is a conventional crosshair finder you are looking at an inverted image while you set it up. The gimbal mount also makes fine target acquisition noticeably harder than on a geared altazimuth head.
5. Celestron Travel Scope 80mm – Best Refractor for Trips and Dark Sites
Celestron Travel Scope 80mm Telescope Kit with Backpack, Smartphone Adapter
80mm aperture
457mm focal length
Fully coated glass
4.5 pounds with backpack
Pros
- Largest aperture in the Celestron Travel Scope line
- Sturdy yet portable at 4.5 pounds
- Smartphone adapter included for phone photos
- No-tool assembly in minutes
Cons
- 457mm focal length keeps magnification modest
- Basic altazimuth mount needs frequent repositioning
The Celestron Travel Scope 80mm is the balance point in the range. It carries an 80mm aperture, which is a real step up in light gathering from the 70mm travel models, and the whole thing weighs 4.5 pounds including the tripod and backpack. The listed Dawes limit of 1.45 arc seconds and a 1.7 degree field of view put it ahead of the 70mm scopes on paper.
Sixty-one percent of the 1791 ratings are five stars, with steady praise for portability, setup speed and crisp lunar views. The smartphone adapter gets singled out repeatedly as a useful addition for casual astrophotography, and at 457mm focal length the phone frames the Moon and larger planets well without the shake you get from heavy magnification.
The bundle includes 20mm and 10mm eyepieces, an erect image diagonal, a 5×24 finderscope and a free download of Starry Night planetarium software. Assembly needs no tools, which matters in a field or a car park where you are not looking forward to fumbling with hex keys in the dark.
It is also a straightforward way to own an 80mm refractor, and 80mm is the aperture most backyard observers actually want. Everything above that step in price rather than in capability for visual work, which is why this one ranks highly despite a modest review count.
Why it suits a backyard observer
At 22.5 inches long and 4.5 pounds, this is the scope you can set up on a folding table at the end of the garden and put away in two minutes when the cloud rolls in. That low friction is what makes a habit, and a habit is what makes an amateur.
Because the aperture is 80mm rather than 70mm, you can push to higher power before the image breaks down. Doubling versus tripling magnification on Jupiter separates the moons more reliably, and the extra light helps on the fainter deep-sky objects that a 70mm scope simply cannot reach from a suburban patio.
Where it falls short
The 457mm focal length is short, so this is a wide-field instrument rather than a planetary one. It sits at f/5.7, and at that fast a ratio the achromatic doublet shows visible purple fringing on bright objects. Step down the power on high-contrast targets and it becomes a non-issue.
The altazimuth mount has no tracking, so objects drift steadily across the field, and at the top of the magnification range you will be adjusting it constantly. If planets are your priority, the longer tubes further down this list hold a much steadier image.
6. Gskyer 90mm AZ Refractor – Best Aperture for the Money
Gskyer Telescope 600x90mm AZ Astronomical Refractor Telescope for Adults
90mm aperture
600mm focal length, f/6.7
Fully coated glass
Three eyepieces plus Barlow
Pros
- Widest aperture in this group for the money
- Three eyepieces plus a 3x Barlow spanning 24x to 120x
- Weighty build that resists wobble at moderate power
- Clear lunar detail with visible Jupiter and Saturn
Cons
- Tripod sits low and forces crouching
- Viewfinder mounts low and needs kneeling
- Shake becomes noticeable at maximum magnification
- No carry bag despite the size and weight
Here is the honest trade-off in this roundup. The Gskyer 90mm shares the widest objective in the group and comes with a three-eyepiece bundle that nothing else here matches, and it arrives on a tripod that cannot be carried comfortably by one adult. It is the pick if the scope will live permanently on one spot of patio, and the wrong pick if you want to take it anywhere.
At 600mm focal length the focal ratio is f/6.7, which sits in a reasonable middle ground. The 90mm aperture gathers substantially more light than the 70mm and 80mm options, so you see more on the Moon, more belts on Jupiter, and you start to reach globular clusters and the brighter nebulae from a suburban backyard.
Sixty-nine percent of the 931 ratings are five stars, with an 11 percent one-star share, so there is a real spread of opinion. The enthusiasm is all about aperture and accessories. The complaints are consistently about the tripod, which adjusts only between 31.5 and 49 inches and sits low for taller observers.
The accessory bundle is genuinely the most complete here: three eyepieces giving 24x, 60x and 120x, a 3x Barlow lens, a 6×30 finderscope, and a 48 degree erecting BAK7 prism for daytime views. That prism is the reason this scope works as both a telescope and a spotting scope, which is a real advantage in daylight.
Why it suits a backyard observer
Aperture is the number that limits everything else you can see, and this scope has as much of it as anything else in the roundup. Going from 80mm to 90mm gives a clear jump in what a suburban patio can reach, including fainter clusters and the brighter deep-sky objects that disappear under light pollution at smaller apertures.
The weight that makes it awkward to carry is also what keeps it steady. At 17.5 pounds the tube barely responds to a gust or a knock on the tripod leg, so at the moderate powers where most people actually observe the image holds still without constant re-centring.
Where it falls short
There is no carry bag, which for a package this size is an odd omission, and the tripod height means taller observers spend a session bent over. The low-mounted viewfinder requires kneeling to align, which adds friction to every setup.
Image shake becomes noticeable at the top of the magnification range, so treat the advertised 120x as an accessory-driven limit rather than a working number. At f/6.7 the achromatic doublet also shows mild colour fringing on bright targets, and occasional focus knob defects do turn up, though manufacturer support resolves them quickly.
7. Celticbird 80mm Refractor – Best for Lunar Contrast
Celticbird Telescope for Adults High Powered, 80mm Aperture 600mm AZ Mount Refractor Telescope for Kids Beginners – Portable Telescopes for Adults Astronomy with Backpack, Phone Adapter, Moon Filter
80mm aperture
600mm focal length, f/6.7
Fully multi-coated lens
5.8 pounds
Pros
- Moon filter adds visible contrast on crater detail
- Tripod adjusts from 17.7 to 52 inches for adults and kids
- Backpack and phone adapter included
- Multi-coated glass at an entry-level cost
Cons
- Magnification ceiling of 66x limits planetary detail
- Reflex finderscope needs adjustment before use
The Celticbird 80mm stands out for one accessory that most of its competitors leave out: a moon filter. It transmits roughly 13 percent of the incoming light, which is what turns a bright washed-out full Moon into a scene with visible crater relief. For a first telescope, that is a bigger practical difference than any glass upgrade at four times the cost.
Seventy percent of the 864 ratings are five stars, and reviewers point at brightness, the filter, and a tripod that works for both adults and children. The adjustable tripod spans 17.7 to 52 inches, which makes it the most height-adaptable mount in this roundup and solves the short-tripod problem that draws complaints on several cheaper 80mm scopes.
Optically you get an 80mm aperture at 600mm focal length, f/6.7, with fully multi-coated high transmission glass. The 20mm and 9mm Kellner eyepieces give 30x and 66x, and the listed field of view is 3.4 degrees, wide enough to sweep star fields rather than just fill the frame with one target.
At 5.8 pounds with a backpack, this is a middle ground between the featherweight travel scopes and the heavy 90mm. It carries comfortably for a short walk to the end of the garden and stays stable enough on the included tripod for lunar and wide-field work.
Why it suits a backyard observer
Full Moon viewing is what most people do in their first year, and the filter makes it worth doing. Watch the terminator and the crater fields around it instead, and this is the scope in the roundup that makes that easy straight out of the box with no additional purchase.
Three years of satisfaction service and 24-hour technical support back it up, which is more cover than most scopes at this level offer. The height-adjustable tripod also means a family can pass it between an adult and a child without anyone crouching.
Where it falls short
The 66x ceiling from the included eyepieces is the real limit. Add a 1.25 inch Barlow and a longer focal length eyepiece and you can reach Jupiter’s moons comfortably, but the bundled set alone will not take you far on the planets.
The 5×24 reflex finderscope needs adjustment before you use it, and the achromatic doublet at f/6.7 still produces mild colour fringing around bright objects. If your priority is planetary detail rather than the Moon, the Celestron AstroMaster at number two serves you better.
8. MEEZAA 90mm Refractor – Best Long Tube for Planets Under 2026
MEEZAA Telescope, Telescope for Adults High Powered Professional, 90mm Aperture 800mm Refractor Telescopes for Astronomy Beginners Stargazing Fully Multi-Coated with Tripod & Phone Adapter & Carry Bag
90mm aperture
800mm focal length, f/8.88
Fully multi-coated glass
Stainless steel tripod
Pros
- Longer 800mm focal length than most 90mm rivals
- Fully multi-coated glass shows Jupiter bands and Saturn's rings
- Light enough for a child to carry yet feels sturdy
- Carry bag and phone adapter support backyard sessions
Cons
- Straight-through finder shows an inverted view
- Focus knob contact makes the scope wobble
- Phone adapter loses magnification and adds misalignment
- Modest deep-sky reach for the aperture
The MEEZAA 90mm sits between the Celestron AstroMaster and the Hawkko in focal length, at 800mm, and it is arguably the best compromise of the three for a backyard. Seventy-one percent of its 820 ratings are five stars, and buyers describe it as an easy first telescope that a child can assemble and carry, with bright lunar craters and visible Jupiter bands and Saturn’s rings.
The focal ratio works out to f/8.88. That matters more than it sounds. At around f/8 and slower, an achromatic doublet has enough room to bring red and blue light to nearly the same focus, so colour fringing on Jupiter and the lunar limb becomes minor rather than constant.
The bundle is strong: 10mm and 25mm Kellner eyepieces, a 3x Barlow lens giving 32x to 240x, an adjustable stainless steel tripod from 28 to 46 inches, a zenith mirror for comfortable high-power viewing, and an accessory tray that keeps eyepieces from rolling off the patio table. A phone adapter and carry bag round it out.
Assembly takes under twenty minutes according to the manual, and the packaging is reported as well protected. That matters for a scope that will live on a patio rather than in a cupboard, since a dented focus knob is a real risk for a glass tube stored outdoors.
Why it suits a backyard observer
An 800mm tube on a tripod you can raise to 46 inches puts the eyepiece near eye level for an adult, which is much more comfortable over a long session than crouching. The zenith mirror lets you observe a target near the zenith without breaking your neck, and the accessory tray keeps everything within reach of the observer’s seat.
For planets the math is favourable. An 800mm focal length gives more magnification per eyepiece than the 600mm scopes, so Jupiter’s belts and the Cassini division in Saturn’s rings start to resolve at powers where a short tube would show a fuzzy disc. Reviewers confirm this in their own observations.
Where it falls short
The straight-through finder shows an inverted image and needs real alignment, which is confusing for a first-time user. It is the most awkward finder on this list for exactly the reason it is cheap.
Two practical problems show up repeatedly in reviews. Touching the focus knob makes the whole scope wobble, which complicates phone focusing, and the phone adapter loses some magnification and introduces misalignment. Deep-sky performance is modest for the aperture size, so this is a planet and Moon instrument rather than a galaxy hunter.
9. Hawkko 90mm f/10 Refractor – Best for Maximum Magnification
Hawkko 90mm Aperture 900mm Telescope for Adults High Powered – Professional Multi-Coated Refractor Telescope for Astronomy Beginners (36X-270X) with AZ Mount, Phone Adapter and Carry Bag
90mm aperture
900mm focal length, f/10
FMC coated optics
5 kg package
Pros
- Best theoretical resolution here at 1.29 arc seconds
- 900mm focal length supports 36x to 270x
- Stainless steel tripod with 360-degree rotation
- Full accessory kit with carry bag and phone adapter
Cons
- Slow f/10 ratio makes the view dimmer than shorter scopes
- Straight-through finder shows an inverted image
- Altazimuth mount lets targets drift during longer sessions
The Hawkko 90mm is the longest tube in this roundup at 900mm, and among the widest apertures here, and that combination is deliberate. A listed Dawes limit of 1.29 arc seconds is the strongest resolving figure among these nine scopes, so this is the one that will hold close double stars and show the most on a well-observed planet.
Sixty-seven percent of the 466 ratings are five stars. Reviewers single out the stainless steel tripod and smooth 360-degree mount movement, along with the completeness of the accessory kit. The 28 to 46 inch height adjustment suits an adult observer properly, and the package includes finderscope, zenith mirror, accessory tray, phone adapter and carry bag.
The optics use full multi-layer coating, listed as raising light transmittance by about 73 percent. Treat that number as a manufacturer claim rather than a measurement, but the practical effect reviewers describe is a bright view for a tube this long, and brightness matters most when you are at high power on a small target.
The eyepiece bundle is 25mm and 10mm Kellner plus a 3x Barlow, spanning 36x to 270x. Like the other scopes here, the top of that range is a paper figure, not a working one. Realistically you will be productive between about 60x and 180x on a night of steady seeing.
Why it suits a backyard observer
The f/10 focal ratio is the quiet hero here. Slow focal ratios reduce the severity of chromatic aberration in an achromatic doublet, which is why this tube and the Celestron AstroMaster look cleaner on Jupiter than the fast 70mm travel scopes do. It also concentrates the same aperture into a narrower beam, so stars are tighter points at the same eyepiece.
At 5 kilograms the whole package is heavy for a carry, but that mass works in your favour on a patio. A heavy tube on a stainless steel tripod barely responds to wind, and steady air means you actually see the magnification you paid for. A two-year warranty is included.
Where it falls short
The long f/10 ratio spreads the same light over a smaller exit pupil, so the image at low power looks dimmer than a short 600mm tube with the same aperture. For sweeping star fields and wide dark sky views the shorter 90mm is more comfortable, and this is not the scope for wide-field work.
The straight-through finder shows an inverted image and needs alignment, and the altazimuth head has no tracking, so at 180x a target crosses the field while you watch it. Budget for a good set of eyepieces before you push the magnification range.
How to Set Up a Refractor Telescope in Your Backyard
Every refractor in this roundup arrives as a sealed tube, which means it needs no collimation before you start. What it does need is time. A glass objective stored indoors or in a shed sits at room temperature while the night air sits near dew point, and until those two match, the image stays soft no matter how good the optics are. Most sealed tubes need 20 to 45 minutes to settle to ambient temperature, and the cool down is longer on a humid night.
Plan your first session around that wait. Set the scope up, point it at the brightest object in the sky, and go make tea. Use the settling time to get organised rather than to stare at a fuzzy Moon through an unfocused eyepiece.
Here is the order that works for us:
First, pick a spot away from direct house, porch and street lighting. A single security light over the patio door will wash out faint deep-sky objects faster than any amount of aperture compensates. Turning off one outdoor light, or draping a jacket over it, frequently outperforms a 20mm upgrade.
Second, set the tripod legs on solid, level ground and check that the whole thing is stable before you load an eyepiece. A scope that rocks when you touch the focus knob will frustrate you all evening.
Third, let the tube settle and use a red light for any chart reading. White light destroys dark adaptation and you lose a good twenty minutes of useful observing.
Fourth, start with the Moon, then Jupiter and Saturn. Bright targets teach you what a good focus feels like before you attempt anything faint, which is the difference between learning to use the scope and abandoning it in a cupboard.
Fifth, use a star chart app to find one object before you go out rather than scanning all night. Forum advice across the astronomy communities we read consistently favours a red dot or reflex sight for aiming, and most beginners who get stuck are stuck because they cannot find the target, not because of the optics.
Finally, expect dew on the front element if the tube is cooler than the surrounding air. It usually clears on its own as the lens warms, and most observers in these communities simply wait it out rather than running a dew heater. If you store the scope on a patio overnight, put the dust cover on before condensation forms.
On light pollution, be realistic about what you are getting. In a typical suburban backyard you are somewhere around Bortle 4 to 6. At that level you will reliably see the Moon in detail, the naked-eye planets, bright globular clusters, the Andromeda galaxy, and the brightest emission nebulae through a modest aperture. Faint galaxy detail and low surface brightness nebulae are what dark sites are for.
That is where portability pays off. Many backyard observers keep a small travel scope like the Celestron 70mm or 80mm on the patio for planets and the Moon, then carry the same tube forty minutes to a genuinely dark site a few times a year for the deep-sky hunting. If your patio setup is also your dark site setup, check the weight and the tripod height before you buy, and read our notes on backyard patio setups for the general problem of making a small outdoor space usable after dark.
Are You Sure You Want a Refractor?
Every general telescope guide tells first-time buyers to start with a Dobsonian reflector, and most of them are optimising for one number: how much aperture you can get for the money. On that measure they are right. A reflector delivers far more light-collecting area per unit of spend than glass does, because a mirror costs roughly the same at 150mm as it does at 70mm while the glass for a refractor has to grow in every dimension.
So the honest answer is that a refractor is not the best first telescope for everyone. It is the best first telescope for a specific set of reasons, and if those reasons are not yours, a Dobsonian will serve you better.
A refractor is right for you if you want the sharpest, highest-contrast image the aperture can produce, if you want a scope that never needs collimating, if you will carry it between the house and the garden or to a dark site, or if you want to photograph the Moon and bright planets with a phone on day one. It is also the right choice for children, because a sealed tube survives a patio far better than an exposed mirror.
Choose a reflector instead if your priority is faint deep-sky objects on a budget, if you want the largest aperture for the least money, or if you already know how to align a Newtonian and do not mind doing it again. Choose a Schmidt-Cassegrain if you want one instrument for both planets and imaging and you will spend the money on a solid mount.
The clearest way to think about it is what you want to look at. Refractors win on the Moon and planets, where contrast and steady magnification matter more than light. Reflectors win on faint fuzzy objects, where light is the only thing that matters. Our MEEZAA 90mm and Celestron AstroMaster 70AZ are the two picks here that genuinely reward a planetary observer, and both are ones we would happily point at Saturn on a clear evening.
One last warning, and it applies to every telescope, not just these. Never point any of these scopes at the Sun without a certified solar filter fitted over the front aperture. An 80mm objective concentrates several hundred times the light of the unaided eye, and a filter from the same box as a beginner kit is not a substitute. Solar viewing damages eyes permanently in seconds.
How to Choose a Backyard Refractor
Aperture is the number that matters most, and it is the one to spend on. Light gathering power scales with the square of the diameter, so moving from 70mm to 90mm gives you about 65 percent more light for a modest step in cost. That is why the 90mm scopes further down this list pull faint objects out of a suburban sky that the 70mm travel scopes simply cannot see.
Focal length is the second number. It is focal length divided by eyepiece focal length that gives magnification, and a long tube gives you more magnification from the same eyepiece plus a narrower, steadier, more contrasty image at planetary power. It also reduces chromatic aberration, because the light is bent less severely on its way through the objective.
Focal ratio decides what the scope is good at. Around f/8 and slower suits planetary work and achromatic glass, because the correction is easier. Faster than about f/5 gives you a wide field for star clusters and sweeping, but pushes an achromat harder and colour fringing becomes obvious on bright objects. Every refractor in this roundup falls between f/5.7 and f/12.9, which is the range where consumer glass stays usable.
Optical class tells you how much colour correction you are buying. Every scope here is an achromatic doublet, which brings two wavelengths to a common focus instead of all three. That is why a purple fringe shows up around Jupiter and the lunar limb. An ED doublet uses extra-low dispersion glass and reduces the fringe considerably. A full apochromat removes it almost entirely, and a Petzval quadruplet goes further by flattening the field for imaging.
Mount is where most backyard regrets happen. A wobbly tripod is the single most reported complaint in the astronomy communities we read, and it is worth more attention than any optical upgrade. Look for a metal tripod with adjustable legs, and check the maximum height against your own height. If the eyepiece ends up at chest level or lower, you will crouch all evening.
A red dot finder or reflex sight beats a bundled finderscope almost every time for pointing. A finderscope shows an inverted image and needs fiddly alignment; a red dot shows you where you are pointing and takes seconds. Several of the scopes here include a reflex finder rather than a red dot, which is a reason to add one later.
Eyepieces are the most common hidden cost. Bundled sets are frequently the weakest part of any kit, and a set of decent 1.25 inch Plossl eyepieces plus a Barlow transforms the experience on any of these scopes more than any other single purchase. Avoid anything with a 0.965 inch focuser, because aftermarket eyepieces of that size are scarce and it signals poor workmanship.
Check what is in the box before you count a scope as complete. Every one of the nine products here is a full kit with a tripod, diagonal, finder and eyepieces included, which is the main reason this roundup skews toward complete telescopes rather than bare optical tube assemblies. An OTA needs a mount, a diagonal and eyepieces before it does anything, and that gap is the value trap that catches first-time buyers.
One last detail for anyone starting out: ignore advertised magnification figures. The number on the box is produced by stacking a cheap eyepiece and a 3x Barlow together, and the result is a dim, shaky, colour-fringed image that shows you less than a moderate power does. Multiply focal length by two for the highest magnification worth using on these scopes, and treat anything beyond that as a paper figure.
Frequently Asked Questions
What is the best telescope for backyard stargazing?
For most backyards the highest-aperture telescope you can carry wins, because light gathering is the limiting factor. A refractor is the better choice when you want sharp, high-contrast, low-maintenance views of the Moon and planets in a sealed tube that never needs collimating. The Gskyer 70mm is our pick for most readers.
Why are refracting telescopes no longer used?
They are still widely used. What changed is that reflectors win on cost per inch of aperture above roughly 150mm of opening, so very large refractors became specialist instruments. Below about 130mm the sealed, collimation-free tube is an advantage no reflector matches, which is exactly where backyard observing sits.
Which refractor telescope is best for viewing planets?
Look for a long focal ratio, around f/8 or slower, which reduces chromatic aberration and gives a steadier, higher-contrast image. The Celestron AstroMaster 70AZ at 900mm focal length is our planetary pick, with the MEEZAA 90mm at 800mm and the Hawkko 90mm at 900mm close behind.
What does achromatism mean in the context of lenses?
An achromatic lens brings two wavelengths of light, typically red and blue, to the same focus instead of all three. Because green light focuses differently, a bright object still shows a faint purple fringe around it, most visible on Jupiter and the lunar limb at high power.
Which telescopes suffer from chromatic aberration?
Cheap achromatic doublets at short focal ratios suffer most, which is why the fast 70mm travel scopes show more fringing than the slower 800mm and 900mm tubes. ED doublets reduce it substantially, and only a true apochromatic triplet removes it almost entirely.
Which is better, a newtonian or refractor telescope?
A reflector gives far more aperture for the money and wins on faint deep-sky targets. A refractor wins on contrast, sharpness, portability, zero collimation and phone astrophotography of the Moon. Choose a reflector if you want faint galaxies and nebulae on a budget, and a refractor if you want a sealed, maintenance-free tube.
How long does a refractor telescope need to cool down?
A sealed refractor tube typically needs 20 to 45 minutes to reach ambient temperature and produce a sharp image, and longer on a humid night. Set it up, point it at the brightest object in the sky, and use the settling time to organise rather than observing.
Do refractors need collimation?
No. The objective lens is fixed in a sealed tube and there is no mirror to adjust, so a refractor needs no collimation between sessions. This is one of its genuine advantages over a Dobsonian reflector and a reason it suits children and outdoor storage.
Bottom Line for Backyard Stargazers
The best refractor telescopes for backyard astronomy in 2026 come down to one question: what do you want to look at? Planets and the Moon, or faint deep-sky objects. For the Moon and planets, buy the Celestron AstroMaster 70AZ and give the tube time to settle. For everything a first scope should do, the Gskyer 70mm is our pick, with by far the most owner feedback behind it. For the darkest skies, the Celestron Travel Scope 80mm goes in a backpack and comes with you.
Whatever you choose, give the tube twenty minutes outside before you judge it, point it at the Moon first, and use a red light. If you are setting up more of your outdoor space, our guides on backyard recovery setups and backyard gazebos cover the furniture side of making a small outdoor space comfortable at night.
