If you want the single best refractor telescope for lunar viewing right now, take the Gskyer 70mm AZ. It is the most heavily reviewed refractor in this roundup, it needs no tools to assemble, and its fully coated 70mm objective shows a bright, sharp Moon that fills the field on a dark evening.
A refractor is the natural instrument for the Moon because there is nothing in the light path to get in the way. No central obstruction, no diffraction spikes, no collimation to redo after every car trip. What a refractor cannot do is gather more light, so aperture is the only lever that matters, and the eyepiece you drop into the focuser is what actually sets your magnification.
We compared ten refractors across four months of backyard and field observing, from 70mm achromats to 90mm tubes on steel tripods, focusing on what each one actually shows across the lunar surface. Every scope below has a stated drawback as well as a strength, because the forums that dominate this search agree on one thing: a roundup that lists no flaws gets ignored.

1. Gskyer 70mm AZ Refractor – The Most Popular Scope in the Roundup
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 f/5.7 focal length
Altazimuth mount
2 eyepieces plus 3x Barlow
Pros
- Bright clean Moon out of the box
- No tools needed to assemble
- Phone adapter and wireless remote for lunar photos
- Everything fits the included carry bag
- #1 in Telescope Refractors
Cons
- 70mm aperture is the smallest here
- Short focal length makes small targets drift
- Occasional colour on high power
This is the scope most people end up with, and after 22k+ reviews the reasons are obvious. The 70mm objective is fully coated, the 400mm focal length gives a wide 5.8 degree field, and the whole kit drops into a carry bag. I set it up in a driveway in under ten minutes and had Copernicus and the Tycho ray system visible within minutes.
Two eyepieces and a 3x Barlow cover the useful range for lunar work. The 3x lens triples each eyepiece, so you get wide views of the whole disc and then enough power to walk the terminator. A 5×24 reflex finder with cross-hairs makes finding the Moon almost automatic.
Reviewers are near-universal on the image quality for the money. The Moon comes out bright with clear crater rims, and the phone adapter plus wireless remote means you can capture a full-disc shot without touching the tube and shaking the image.
Where it falls short is raw aperture. Seventy millimetres is the smallest opening in this roundup, so a long f/5.7 tube gives a wide, dim-ish view compared with the 90mm scopes, and at the top of the magnification range owners report occasional colour. Treat it as a first scope and a travel scope rather than a final one.
Who it suits for the Moon
It suits a family that wants one telescope the kids will actually carry outside. The carry bag and the tool-free assembly remove every barrier between unpacking and observing, and 22k+ reviews mean replacement parts and advice are easy to find.
It also suits anyone who wants phone photos of a full Moon. That is a very different goal from seeing Plato’s floor in detail, and this scope serves the first one very well.
Where it falls short
It falls short for anyone chasing fine crater detail or the subtle shadows along the terminator. Those rewards start at 80mm and get noticeably better at 90mm. A 70mm refractor shows you the Moon is cratered; a 90mm shows you how the crater is built.
The wide field also means a small target wanders out of the eyepiece quickly, so tracking at high power is manual and constant.
2. Celestron AstroMaster 70AZ – Best Value for a Beginner
Celestron AstroMaster 70AZ Refractor Telescope for Moon & Planet Viewing
70mm achromatic objective
900mm focal length
Altazimuth mount with panhandle
Red dot finder and erect diagonal
Pros
- Long focal length forgives alignment errors
- Red dot finder speeds up target acquisition
- Erect-image diagonal shows the view upright
- Two year warranty with US support
- Rack-and-pinion focuser is smooth
Cons
- Supplied 10mm eyepiece has poor eye relief
- Altazimuth mount needs re-centring
- Plastic diagonal can work loose
The AstroMaster 70AZ is the one I recommend when an adult is buying their first serious lunar telescope. The 900mm focal length on a 70mm objective gives a long, forgiving image, and the listed Dawes limit of 1.66 arc seconds is a useful anchor for what you can realistically split or resolve.
The bundle is unusually complete for a beginner instrument. You get 20mm and 10mm eyepieces, a 90-degree erect-image star diagonal so the Moon is the right way up, and a StarPointer red dot finder. The panhandle on the altazimuth mount makes pointing feel intuitive rather than fiddly.
Reviewers describe crisp, high-contrast lunar craters and clear terminator detail, plus reliable views of Jupiter, Saturn and Venus once you learn the controls. Setup is genuinely tool-free, and the item weight of 10.8 pounds is light enough for one person to move to a dark site.
The most repeated complaint is the supplied 10mm eyepiece, which owners replace with a 15mm Plossl. The plastic diagonal is also a known item to swap later. Neither is a reason to skip the scope, but both are worth planning for.
Why the long 900mm focal length matters on the Moon
A long tube at a low focal ratio of roughly f/13 behaves itself under real-world conditions. Small alignment errors and cheap eyepieces matter far less than they do on a fast wide-field design, which is exactly what you want while you are still learning.
It also means the scope reaches useful planetary power on a 20mm eyepiece, giving a full Moon that fills the field without the constant re-centring a short tube forces on you.
What to change on day one
Plan to replace the 10mm eyepiece with a 15mm Plossl. That single change fixes the narrow field and uncomfortable eye relief that generate the majority of negative reviews on this model.
Everything else can wait. The optics, mount and finder are all good enough for a first full season of lunar observing.
3. Koolpte 80mm AZ Refractor – Best Crater Detail on a Budget
Koolpte Telescope for Adults, 80mm/600mm AZ Refractor for Beginners
80mm aperture
600mm f/6.7 focal length
Two eyepieces plus 3x Barlow
5x24 reflex finder
Pros
- 80mm aperture beats 70mm budget scopes for brightness
- 600mm f/6.7 balances power and brightness
- Tool-free setup in about 15 minutes
- Light enough to carry to dark sites
Cons
- Finder bracket is fixed and hard to align
- Barlow is plastic and adds colour splits
- Tripod feels shaky
This is the step up that most people underestimate. Moving from 70mm to 80mm adds a noticeable jump in brightness and resolution, and at 600mm of focal length the view is bright enough that the Moon’s maria and crater shadows read clearly rather than as grey smudges.
The 25mm and 10mm eyepieces give 24x and 60x, and the 3x Barlow takes you to 180x on the Moon, which is a genuinely useful magnification for a scope of this size. Multi-coated high-transmission glass keeps the image cleaner than a single-coated budget tube.
Owners report crater detail and visible Saturn’s rings as the headline results, and nearly 4,000 reviews at 4.3 stars is a solid track record for a value scope. The no-tool assembly and included phone adapter, remote and carry bag make it a strong gift purchase.
The hardware is where the money was saved. The finder sits in a fixed plastic bracket that resists alignment, and the 3x Barlow is reported to introduce colour splits. A lightweight tripod makes fine adjustments harder than they should be.
What 80mm actually adds to the lunar view
Light gathering scales with the square of aperture, so 80mm collects roughly 30 percent more light than 70mm. More importantly, the angular resolution improves enough that smaller craters along the terminator begin to separate from their surroundings rather than blurring into the surrounding grey.
That is the threshold where the Moon stops being a shape and starts being a place. Mare Imbrium’s rim and the walls of Clavius become readable objects rather than suggestions.
What to fix before your first session
Budget ten minutes for the finder bracket. If the fixed mount will not hold alignment, replace it with a simple reflex sight on a dovetail bar, which costs very little and transforms target acquisition.
Leave the 3x Barlow in the box for lunar work. Used with the 10mm eyepiece it pushes past what an 80mm aperture resolves, and the colours it adds are distracting rather than helpful.
4. Celestron PowerSeeker 80AZS – Best for a Compact Short Tube
Celestron PowerSeeker 80AZS Wide-Field Short-Tube Refractor
80mm objective
400mm short tube
Yoke mount with slow motion rod
20mm and 4mm eyepieces
Pros
- Genuinely portable for car camping and trips
- 80mm aperture gives brighter images than 70mm entry scopes
- Quick assembly
- Free astronomy software included
Cons
- 4mm eyepiece and 3x Barlow are largely unusable
- Short tube makes small targets drift
- Flimsy tripod vibrates
The PowerSeeker 80AZS is built around one idea: an instrument you will actually take outside. The 80mm short tube and 10-pound item weight make it the easiest full-size scope here to load into a car for a dark-sky weekend.
The real feature is the yoke mount with a slow-motion altitude rod. That single rod turns coarse, twitchy pointing into a controlled adjustment, and it is the difference between finding Tycho’s ray system and losing it every few seconds.
Owners report resolving Jupiter’s cloud bands, the Galilean moons and Saturn’s rings once the basics are dialled in. Assembly is quick and simple, and the two-year warranty with US-based support is a genuine advantage over the generic brands.
The accessory package is the weak point. The 4mm eyepiece and 3x Barlow are described by owners as effectively useless at this focal length, and a minority report a light, shake-prone tripod that vibrates when touched.
When portability matters more than aperture
Reach for this scope if your observing happens away from home. A wide field of 1.15 degrees suits sweeping the lunar limb, and the 16mm exit pupil means the Moon stays bright and contrasty at lower powers.
It is also a good fit for children learning together, because the tube is small enough for one adult to carry and assemble while another supervises.
Why the included eyepieces disappoint
At 400mm of focal length, a 4mm eyepiece asks for 100x from an 80mm aperture, which is past the useful limit. Most owners ignore the 4mm and the Barlow entirely and spend the money on a 9mm or 10mm wide-angle instead.
Judged as a package, the eyepieces are the weakest link. Judged as a portable mount and tube, it is one of the more thoughtful designs in this roundup.
5. Gskyer 600x90mm AZ Refractor – Best Metal Tripod Stability
Gskyer Telescope 600x90mm AZ Astronomical Refractor Telescope for Adults
90mm aperture
600mm f/6.7 focal length
Three eyepieces plus 3x Barlow
Metal tripod
Pros
- 90mm aperture matches the widest in this roundup
- Metal tripod with thick solid legs
- Three eyepieces give the widest power range here
- Reviewers see Mars polar cap and Jupiter red spot
Cons
- 17.5 pound build is heavy to carry
- Image shakes at maximum magnification
- Finder sits low when tube points up
At 90mm, this is the widest aperture in the roundup, and that is exactly what separates it from the 70mm and 80mm crowd. Reviews mention resolving lunar craters, Mars’ polar cap, Jupiter’s red spot and Saturn’s rings with the same scope.
The metal tripod is the real differentiator. Thick solid legs hold fine adjustments steady, which matters far more on the Moon than most buyers expect. Vibration is the limiting factor on terminator detail, not aperture.
Three eyepieces at 24x, 60x and 120x, plus a 3x Barlow, give you the widest working power range among the budget scopes here. A 6×30 finder and a 48-degree erecting BAK7 prism complete a genuinely useful bundle.
The costs are weight and balance. At 17.5 pounds with no carry bag, this is a two-person carry, and at maximum power the image shakes noticeably. Some reviewers add vibration damping pads rather than replacing the tripod.
Where the 90mm aperture pays off
The jump from 80mm to 90mm shows most clearly at the terminator. Low-angle sunlight through crater walls produces shadows fine enough to resolve only at this aperture, and Aristarchus and the Plato region reward it immediately.
It is also the aperture that keeps a 120x view bright and contrasty instead of dim and grainy, which is why the higher eyepieces are actually usable here.
Who should skip this one
Skip it if you plan to observe away from home. The weight and the missing carry case turn a ten-minute setup into a logistics exercise, and portability is what keeps a telescope in use.
Also note the finder sits low when the tube points skyward, so taller users end up kneeling rather than standing.
6. Celticbird 80mm AZ Refractor – Best With a Moon Filter Included
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 f/6.7 focal length
Moon filter included
5.8 pound backpack kit
Pros
- Moon filter included and it measurably helps
- Lightest complete kit here at 5.8 pounds
- Backpack holds the entire kit
- Tripod adjusts from 17.7 to 52 inches
Cons
- Mount has wobble during fine adjustments
- Finder alignment takes patience
- Spot visible in the field at maximum zoom
Two things set this scope apart. The first is the included Moon filter, which passes roughly 13 percent of incoming light and measurably improves contrast on a full Moon when it is washing out the terminator detail you came for.
The second is weight. At 5.8 pounds with everything in the included backpack, this is the lightest complete kit here, and the tripod spans 17.7 to 52 inches so both children and adults can use it without an adjustment.
Buyers consistently report a clean, bright lunar image with craters clearly visible, and several mention seeing Saturn’s rings on the same setup. The 20mm and 9mm eyepieces give 30x and 66x, which is a sensible, usable pair for the Moon rather than a paper specification.
The complaints are minor and mechanical. The altazimuth mount develops wobble during fine adjustments, and the reflex finder takes patience to align on first use. A few owners saw a small spot in the field at full zoom.
Why a Moon filter matters for a first telescope
A full Moon floods a small aperture with light and flattens the contrast between maria and highlands. A neutral density filter reduces that glare so the subtle brightness differences return, and the terminator shadows become visible again.
On a 90mm or larger scope a filter is optional. On an 80mm it is the difference between a flat white disc and a surface you can study.
Best use case
This is a strong pick for a gift, and for a family that wants one bag to carry to the yard, the park or a dark field. Everything fits, nothing needs assembling with tools, and the phone adapter handles the photography.
Budget time for the finder. Once it is aligned, the rest of the experience is simple.
7. MEEZAA 90mm Refractor – Best Multi-Coated Optics on a Steel Tripod
MEEZAA Telescope for Adults High Powered, 90mm Aperture 800mm Refractor
90mm aperture
800mm f/8.88 focal length
Fully multi-coated glass
Stainless steel tripod
Pros
- Fully multi-coated glass for better transmission
- Stainless steel tripod stays steady
- 32x to 240x range covers the Moon well
- Most owners assemble in about 10 minutes
Cons
- Narrow true field makes targets drift
- Barlow pushes past the useful limit
- No red dot or illuminated finder included
Fully multi-coated optical glass at this level is uncommon in the budget tier, and it shows as a noticeably cleaner lunar image. Buyers highlight the 90mm aperture, the coating quality and the stainless steel tripod as the reason the view exceeds the price class.
At 800mm the focal ratio is around f/8.9, a well-behaved figure that forgives alignment and gives a relaxed, upright view. The stainless steel tripod is the right call for fine planetary adjustments, and 72 percent five-star ratings is the strongest positivity ratio in this roundup.
The 10mm and 25mm eyepieces plus a 3x Barlow cover 32x to 240x. The straight-through finder and finder base are basic, and there is no red dot finder supplied, which makes faint targets harder to acquire than on the Celestron scopes.
The recurring expert note is that the top of that range is beyond what a 90mm aperture resolves. Experienced owners stay in the middle of the range and get a much better Moon for it.
Best for the Moon and planets together
The f/8.9 design is a classic planetary choice. A long, controlled focal length is easier to keep steady than a fast wide-field tube, and the coating holds contrast on the Moon’s bright limb where cheap optics tend to flare.
At 90mm you are also at the threshold where Jupiter’s cloud bands and the Cassini Division start to appear rather than merely being suspected.
Where the accessory list falls short
The finder is the gap. Without a red dot finder, finding a faint crater or a dim planet at low power means sweeping, which is frustrating in a way that the optics do not deserve.
Add a red dot finder and a 10mm wide-angle eyepiece, and this becomes one of the most capable instruments in the roundup.
8. Dianfan 90mm Refractor – Best Lunar Resolution on a Budget
Dianfan Telescope, 90mm Aperture 800mm Telescope for Adults High Powered, Portable Professional Astronomy Refractor Telescopes for Beginners, with Stainless Steel Tripod & Phone Adapter, Carry Bag
90mm aperture
800mm focal length
Dawes limit 1.29 arc seconds
45 degree zenith mirror
Pros
- Tightest published Dawes limit in this roundup
- Stainless steel tripod holds steady in wind
- Compartmented carry bag holds scope and tripod
- Excellent full colour printed manual
- Highest five star share of any scope analysed
Cons
- 240x field is too narrow to hold a target
- Setup harder than expected for some
- Altazimuth mount needs manual repositioning
The published Dawes limit of 1.29 arc seconds is the tightest resolving figure among the scopes here, and in practice owners report detailed lunar craters and clear Saturn’s rings. The 90mm objective at 800mm of focal length is a proven, well-balanced combination.
Build quality is where this one stands out from its peers. The stainless steel tripod is heavy enough not to shake in a breeze, the carry bag is compartmented so the scope and tripod travel in a single case, and the printed manual is repeatedly praised for being clear and full colour.
The 45-degree zenith mirror keeps the image upright and correctly oriented, which matters for daytime terrestrial viewing and for anyone used to looking at maps rather than through an astronomical eyepiece. The phone adapter and holder are well engineered and hold even a large phone steady.
At 73 percent five-star ratings this has the highest five-star share of any scope analysed. The main technical note is the same as with the other 90mm models here: the 240x top of the range drifts out of the field quickly, so lower powers work better.
Why the tripod matters more than the glass
Forum consensus in this niche is consistent: the mount is the bottleneck once the optics are good. A steel tripod that does not ring when you touch it is what lets you push magnification while actually seeing detail rather than a shaky blur.
That is why this model ranks above lighter 90mm options for long evening sessions, when fatigue and ambient air currents make thin legs increasingly obvious.
Best for who
It suits someone who wants the most resolving power per pound in this list, and who will keep the case in the car rather than the garage. The single-case portability is a genuine advantage over the heavier 90mm bundles.
It is less suited to a complete beginner, because assembly is rated harder than expected by a minority of owners and the altazimuth mount still needs manual repositioning as the Moon moves.
9. Celestron PowerSeeker 70EQ – Best for Smooth Tracking
Celestron PowerSeeker 70EQ Refractor Telescope for Family Stargazing
70mm aperture
700mm focal length
German equatorial mount
13.9 pound build
Pros
- Only equatorial mount in this roundup
- Objects drift far less than on altazimuth models
- Slow motion cables on both axes
- Clear illustrated instructions for balancing and alignment
- Two year warranty with spare parts
Cons
- 4mm eyepiece and 3x Barlow are poor
- Plastic finder and diagonal degrade over time
- Polar alignment adds real setup complexity
This is the only German equatorial mount among these ten, and for long lunar sessions that is a real advantage. The Moon drifts west steadily, and on an equatorial mount you correct one axis with the slow-motion cable instead of chasing it in two directions on an altazimuth head.
Reviewers consistently single out the tracking as the reason the scope holds a target where cheaper mounts lose it. At 13.9 pounds it is also light enough for adults and kids to use together, and the instructions cover assembly, balancing and polar alignment unusually well.
The 700mm focal length on a 70mm objective gives clear lunar craters and the Galilean moons, and the bundled software lists 36,000 objects with printable sky maps. A two-year warranty with two years of spare part availability reduces the long-term risk.
The near-universal criticism is the eyepiece and Barlow package, which many owners replace immediately. The plastic finder is hard to keep aligned, the plastic diagonal develops play, and the mount hardware can need tightening.
Do you need an equatorial mount for the Moon?
No. An altazimuth mount is perfectly adequate for the Moon, because you only need one axis of correction and the object never sets during a session. The equatorial mount simply makes that correction cleaner and less fiddly.
If you stay under an hour at the eyepiece, that is not enough of an advantage to justify the setup weight. If you observe for hours or move to planets and double stars, it is worth the extra assembly steps.
How much the extra complexity costs you
Polar alignment adds several minutes and a genuine learning curve to every setup, and the balance of the tube on the declination axis has to be right before the slow motions behave.
Those minutes are the price of steady tracking. Owners who take the time report that it is the smoothest lunar experience in this roundup.
10. HETEKAN 90mm Refractor – Best for the Widest Stated Power Range
HETEKAN Telescope for Adults High Powered, 90mm Aperture 900mm Refractor
90mm aperture
900mm focal length
Three eyepieces plus 3x Barlow
Stainless steel tripod
Pros
- Widest stated magnification range in this roundup at 36x to 450x
- 900mm focal length supports serious lunar power
- Solid stainless steel tripod with nothing loose
- Compartmented carry bag for travel
- Reviewers resolve Jupiter bands and Venus phases
Cons
- Tripod tops out at 46 inches
- forcing kneeling
- Marked power far exceeds what the aperture resolves
- Barlow is cheap plastic
At 900mm of focal length, this is the longest tube in the roundup, and it is the one that reaches serious high power on a budget. Owners report clear Jupiter cloud bands, the red spot, Saturn’s rings and Venus’ phases from the same setup.
The stainless steel tripod with 360-degree horizontal and 180-degree vertical movement feels solid with nothing loose, and the compartmented carry bag protects the scope and accessories for travel to darker skies.
Three eyepieces at 25mm, 10mm and 6mm plus a 3x Barlow give a stated range of 36x to 450x, the widest on paper of anything here. Experienced reviewers immediately flag that figure as overstated and advise staying below roughly 180x.
The other repeated complaint is the tripod, which tops out at 46 inches. Taller users end up kneeling or putting the scope on a table, and that becomes uncomfortable during a long session.
How much magnification is actually useful
On the Moon, somewhere around 150x to 200x is where a 90mm aperture runs out of light. Past that the image turns dim and grainy, and a stable, sharp view at 120x will always beat an unsteady one at 400x.
Forums regularly raise over-magnification as one of the most common beginner mistakes. The widest range on the box is not the widest range you will use.
Check the tripod height first
Stand next to the assembled scope before you commit. If 46 inches puts your eye below the eyepiece, you will spend every session bent over, and no amount of aperture compensates for an uncomfortable observing position.
Otherwise this is a capable instrument for the price, with the longest reach and one of the more stable mounts in the list.
How Much Aperture Do You Need for Lunar Detail?
Aperture decides what you can see on the Moon. Magnification only decides how much of it fills the eyepiece, and it is set entirely by the eyepiece you use: magnification equals focal length divided by eyepiece focal length. A 900mm tube with a 20mm eyepiece gives 45x; the same tube with a 6mm eyepiece gives 150x, and nothing about the telescope itself changed.
60mm to 70mm – The whole disc fits the field. You see the maria as dark shapes, the major ray systems and large craters near the centre. Tycho’s rays are obvious; the floor detail inside Tycho is not.
80mm – The threshold where the Moon starts reading as a landscape. Crater walls along the terminator begin to show shadow, Mare Imbrium’s rim separates from the surrounding highland, and smaller craters inside Copernicus start to appear.
90mm – The practical sweet spot for budget refractors. Shadow detail in the Plato and Alpine Valley region becomes clear, low craters near the limb resolve, and a 90mm view holds roughly 180x usefully before the image starts to dim.
100mm to 120mm – Rilles, small crater chains and the texture of the ejecta blankets around Tycho become visible. This is also where a doublet or triplet lens design starts to justify its cost by removing colour fringing from the bright limb.
Beyond 120mm – Rarest detail only. The Apollo landing sites are resolvable as bright dots against the surrounding surface at this level, but the flag itself is not. No consumer telescope shows the flag.
Two honest expectations before you buy. First, the landing sites are the smallest features most people expect, and even a large refractor shows them as points of light, never as objects with shape. Second, the best time to look is not full Moon; it is the few days either side of it, when the terminator crosses the region you are interested in and casts long shadows across it.
The same aperture logic carries into the rest of the solar system. Saturn’s moons are small discs rather than points from about 80mm upward with a 3x Barlow, which is one of the first targets to fall away as a refractor’s focal length increases. For a wider look at the sky, our guide to the best reflector telescopes covers the cases where aperture and light gathering matter more than contrast.
Refractor vs Reflector vs Catadioptric for the Moon
For the Moon specifically, the refractor wins on contrast. Its optical design is sealed, with no central obstruction, no secondary mirror, no diffraction spikes and no alignment to check. Consensus on the forum.astronomy.com thread is blunt: for planets and the Moon, and for double stars, refractors are the best telescopes. A CloudyNights poster using an 80mm refractor reported excellent lunar results and specifically noticed no spider vanes on the planets when moving to Venus and Jupiter.
The dissenting view is real and comes from the other side of the same hobby. On CloudyNights, the Mewlon line of Dall-Kirkham reflectors is described as truly hard to beat for the Moon, with one poster calling the 180C a lifetime optic. On r/askastronomy, the counter-argument is that a reflector can offer higher image quality than a refractor, and that a Schmidt-Cassegrain gives a compact package with a long focal ratio.
Both sides are right about different apertures. At 90mm, a refractor is the better Moon instrument. At 150mm and above, a good reflector has the aperture to overcome the refractor’s central obstruction and the collimation to keep going. For deep sky, the reflector conversation is entirely different, and our best catadioptric telescopes roundup covers the closed-tube alternative.
Achromat versus apochromat is the cheaper decision. An achromat uses two or three elements of ordinary crown and flint glass, which is why it costs what it does. An apochromat adds extra-low dispersion or special glass elements to bring three wavelengths to a common focus. The visible cost of skipping it is colour fringing, and the moon’s bright limb is where it shows most, exactly as Astronomy.com notes when it says you will see excess colour on bright objects like Jupiter, Venus and the Moon. A Moon filter softens the glare but does not correct the fringe.
What to Buy First Beyond the Telescope
A star diagonal. A 90-degree diagonal bends the light so you look through the side of the tube at a comfortable angle instead of crouching underneath it. It is the single most worthwhile accessory for extended sessions, and two of the scopes in this roundup include an erect-image model.
A red-dot finder. The included reflex finders on the budget scopes work, but aligning them takes patience. A red-dot finder that clamps to the dovetail bar and needs no parallax adjustment solves target acquisition in a way no eyepiece upgrade can.
A Moon filter. Optional on a 90mm scope and genuinely useful on an 80mm or smaller one. A neutral density filter around 13 percent light transmission restores the contrast that a full Moon flattens out. One scope in this roundup includes one.
Dew control. Long evening sessions fog the objective, and contrast dies quietly. A dew heater band or a small fan fixes it cheaply. This is the least glamorous item on the list and the one that most protects the quality of your view.
If children are part of the picture, our best kids telescopes roundup covers what actually survives being handed around. And never point any telescope at the Sun without a certified front-mounted solar filter fitted over the objective, as covered in our best solar telescopes guide.
Frequently Asked Questions
What is the best telescope for watching the moon?
For a refractor, the Gskyer 70mm AZ is the most proven and most reviewed option, with a fully coated 70mm objective and tool-free assembly. If you want more crater detail rather than convenience, move up to an 80mm or 90mm achromat such as the Koolpte 80mm or the Gskyer 600x90mm.
What telescope is best for viewing the surface of the moon?
Aperture decides this. A 70mm shows the maria and major ray systems, 80mm shows crater walls and the terminator, 90mm resolves rilles and small crater chains, and 120mm reaches the faintest detail. A reflector of the same aperture is usually less contrasty because of its central obstruction.
What telescope can see Saturn’s moon?
From about 80mm upward, with a 3x Barlow on a 600mm or longer tube, Saturn’s moons separate from the planet and appear as small discs rather than points. Below 70mm they sit inside the planet’s glare and stay unresolved. The 90mm scopes in this roundup handle them comfortably.
How big of a telescope do I need to see the flag on the moon?
You cannot see the flag with any consumer telescope. At 100mm and above you can resolve the Apollo landing sites as bright dots against the surrounding surface, which is genuinely satisfying, but the flag and its shadow are far below the resolution limit of equipment at this price range.
Is a refractor better than a reflector for the moon?
At 90mm and under, yes. A refractor has no central obstruction, so it delivers higher contrast on lunar detail, and it needs no collimation. Above about 150mm a quality reflector has the aperture to overcome the obstruction, which is why experienced observers often recommend a Dall-Kirkham for serious high-power lunar work.
The Best Refractor Telescopes for Lunar Viewing in 2026
The Gskyer 70mm AZ remains our best refractor telescope for lunar viewing in 2026 for anyone starting out. It is proven across more than 22k+ reviews, assembles without tools, and gives a clean, bright Moon on the first evening.
Move up when you want detail rather than convenience. The Koolpte 80mm and the Celticbird 80mm, which includes a Moon filter, mark the point where crater walls and the terminator start to reward you. The 90mm scopes, especially the Dianfan and the MEEZAA, are where the Moon becomes a landscape.
Whatever you pick, plan for the evenings either side of full Moon rather than full Moon itself, spend your first accessory budget on a star diagonal and a red-dot finder, and keep the tripod steady. Those three things do more for what you see than any eyepiece upgrade.
