If you want the best telescopes under 500 right now, the Gskyer 70mm AZ Refractor is the one I keep coming back to. With more than twenty thousand owner reviews behind it, it is by far the most proven starter scope at this price, and nothing else on this list has that much real-world evidence attached to it.
Weighing aperture first is not a party trick from telescope people. r/telescopes regulars repeat the same advice over and over: at this price tier, light grasp beats brand name, glass coatings, and motorized pointing every single time. When you compare scopes, compare mirror or lens diameter before anything else on the spec sheet.
That said, this is not a list of ten identical scopes from one brand. The ten below run from an 840g travel refractor to a 150mm reflector on a German equatorial mount, and they split fairly cleanly into three camps: 70-90mm refractors for Moon, planets and daytime use, and 127-150mm reflectors for anyone who wants to see faint nebulae and galaxies. Every scope listed here sits under the 500-dollar ceiling and carries a review count deep enough to trust.
I have been running these same decision rules on budget scopes for years, and the pattern holds: the first telescope matters less than the first ten clear nights. If you are still comparing spec sheets, our beginner telescope guide under 500 covers the basics in more depth. This page is the shortlist, tested against real owner reviews rather than marketing copy.

1. Gskyer 70mm AZ Refractor – the most-owned starter scope
Gskyer Telescope, 70mm Aperture 400mm AZ Mount Astronomical Refracting Telescope for Kids Beginners – Travel Telescope with Carry Bag, Phone Adapter and Wireless Remote.
Aperture: 70mm
Focal length: 400mm
Mount: altazimuth tripod
Finder: 5x24 reflex
Pros
- Fully coated 70mm glass optics
- Two eyepieces plus a 3x Barlow
- 5x24 reflex finder with crosshairs
- Phone adapter and wireless remote
- Carry bag included
Cons
- No tracking drive so objects drift
- Entry-level optics soften at high power
- Finder needs aligning to the tube first
Twenty-two thousand reviews is a useful signal on its own. This Gskyer 70mm is the highest-volume scope in the group, and the pattern across those reviews is consistent: setup takes minutes with no tools, and the Moon looks good within a week of arriving.
The optics are a fully coated 70mm refractor on a 400mm focal length, which works out to about f/5.7. That is a wide, bright view rather than a planet-hunter, and owners tend to be delighted by crater detail near the terminator and by Jupiter’s four moons.
Two eyepieces and a 3x Barlow come in the box, along with a smartphone adapter and a wireless shutter remote. That bundle is genuinely the reason this scope wins on value: you can mount a phone for first-night photos without buying another accessory.
The honest weakness is tracking. This is a manual altazimuth mount, so an object walks out of the field every couple of minutes at moderate power. On a 70mm aperture that is survivable; on a 150mm reflector it would be miserable.
Reviewers also note that the finder must be aligned with the main tube before it is usable, a five-minute job that catches out first-time owners. Overall it stays crisp at low power and goes soft past its modest maximum magnification.
Who this scope suits
For kids aged ten and up, families sharing one scope on a suburban driveway, and anyone who wants lunar and Jupiter views without a steep learning curve. The carry bag means it lives in a closet rather than a garage, which matters for people in apartments.
It also works well as a grab-and-go birding and daytime scope thanks to the included erecting diagonal. If your idea of stargazing is pointing at the Moon after dinner, this does that job well.
Who should look elsewhere
If you want to hunt faint galaxies and globular clusters from a dark site, 70mm simply does not collect enough light. Move up to the PowerSeeker 127EQ or one of the 150mm reflectors instead.
Avoid it too if you plan to sit on one target for an hour with a video camera. No tracking means constant nudging, and video will show it.
2. Celestron Travel Scope 70mm – packed for a backpack
Celestron Travel Scope 70mm Beginner Portable Telescope with Backpack
Aperture: 70mm
Focal length: 400mm
Weight: 4.2 pounds
Box: backpack kit
Pros
- No-tool setup in minutes
- Preassembled tripod and tube
- Padded backpack holds full kit
- 20mm and 10mm eyepieces
- Starry Night software included
Cons
- Small aperture limits faint targets
- Short focal length caps magnification
- Manual alt-az mount needs repositioning
The Celestron Travel Scope is the oldest-running recommendation in beginner astronomy, and the reason is simple logistics: everything fits in the backpack that comes with it. At 4.2 pounds it is the most complete travel kit here.
You get a fully coated 70mm refractor, a 400mm focal length, a 20mm and 10mm eyepiece, a 45 degree erect image diagonal, a 5×24 finderscope, and free Starry Night software. The preassembled tripod means you can be looking at the Moon within minutes of unpacking.
The two-year limited warranty and the sheer volume of owner feedback give me more confidence in this one than the price tag suggests. Reviewers repeatedly call it dependable rather than impressive, which is exactly what a first scope should be.
What you give up is light. At 70mm the Orion Nebula is a fuzzy patch rather than a structured object, and Saturn’s rings are visible but faint compared with what a 130mm or 150mm mirror shows on the same night.
The field of view rating of 1.43 degrees also tells you this is a scope for a single target at a time, not wide sweeping views of the Milky Way.
Who this scope suits
Anyone who genuinely travels. This is the pick for campsite observing, cabin weekends, and taking a scope to a dark site when your car packing is limited. The erect image diagonal makes daytime land viewing genuinely useful too.
It is also a good second scope to lend out, since the backpack makes it easy to hand to a friend or relative who lives far from a dark sky.
Who should look elsewhere
Skip it if your observing site is a light-polluted city backyard and your targets are galaxies. The aperture ceiling here is the binding constraint, and no amount of eyepiece upgrading fixes it.
It is also not the choice for a complete beginner with zero experience who wants motorized pointing. Expect to learn star-hopping with a planisphere.
3. Celestron PowerSeeker 127EQ – the most light per dollar
Celestron PowerSeeker 127EQ Reflector Telescope for Home Astronomy
Aperture: 127mm
Focal length: 1000mm
Mount: German equatorial
Weight: 13 pounds
Pros
- 127mm aperture for deep-sky objects
- Slow-motion altitude rod aids tracking
- 1000mm focal length for planets
- Barlow plus two eyepieces
- Light enough for campsite trips
Cons
- Newtonian mirrors arrive out of collimation
- EQ backlash with plastic parts
- Supplied 4mm eyepiece is faint
This is the aperture-per-dollar answer to what is the best telescope to buy for the money. A 127mm primary mirror on a manual German equatorial mount, at a price that leaves room in the budget for better eyepieces later.
The jump from a 70mm refractor to a 127mm reflector is the single biggest visual upgrade available under 500. The mirror collects about three times the light, which turns the Orion Nebula from a smudge into a shape and makes globular clusters resolvable rather than grainy.
You also get a 1000mm focal length, which supports the magnification needed for Jupiter’s belts and Saturn’s rings, plus aluminum and SiO2 coated mirrors, a 20mm and 4mm eyepiece, and a 3x Barlow.
At 13 pounds it is portable enough for a dark-site trip, and the slow-motion altitude rod lets you nudge an object along without disturbing the whole mount.
Now the difficult part. This is the most polarizing scope in the group at 4.1 stars, and the split is entirely about collimation. A large share of reviews are dedicated to mirror collimation technique, and buyers who learn it report sharp planets and crisp deep-sky detail.
Owners who skip that step describe persistently soft images. Newtonians do need periodic alignment, and this one is no exception.
Who this scope suits
A beginner who will spend ten evenings in a row learning the sky and wants real deep-sky targets from year one. It suits people who enjoy a mechanical project and are not put off by collimation and polar alignment.
It also suits a family with a dark site within driving distance, since 13 pounds and a tripod are manageable for two people.
Who should look elsewhere
If setup frustration would end your hobby before it started, pick an altazimuth scope instead. The equatorial mount here has noticeable backlash and light plastic components, which is a real annoyance during fine planetary work.
Also avoid it if you want to photograph. A purely manual equatorial mount with no motor drive is not an astrophotography platform.
4. Koolpte 80mm AZ Refractor – phone-ready and cheap
Koolpte Telescope for Adults & Beginner Astronomers – 80mm Aperture 600mm Fully Multi-Coated High Transmission Coatings with AZ Mount Tripod Phone Adapter, Carrying Bag, Wireless Control.
Aperture: 80mm
Focal length: 600mm
Mount: altazimuth tripod
Finder: 5x24 reflex
Pros
- Fully multi-coated 80mm optics
- 25mm and 10mm eyepieces plus 3x Barlow
- 5x24 finder included
- Phone adapter and wireless remote
- No-tool setup
Cons
- No tracking so planets drift
- Short 600mm focal length
- Kellner eyepieces blur past moderate power
The Koolpte 80mm is the value pick for anyone who wants multi-coated glass and a phone adapter without leaving the ultra-budget tier. At 4.3 stars across nearly 4000 reviews, the ratings track closely with the Gskyer 70mm above it.
Optically it is a step up in a specific way. The 80mm aperture is fully multi-coated with high-transmission coatings, and the 600mm focal length gives about f/6.7, a reasonable compromise between wide fields and planetary reach.
Owners consistently praise the accessory bundle: two eyepieces, a 3x Barlow spanning 24x to 180x, a 5×24 finder, a phone adapter, a wireless remote, and a carry bag.
The critical feedback thread runs through every review: there is no tracking drive at all. Planets drift out of view, and at the top of the magnification range the Kellner eyepieces go soft before the optics do.
Treat the 180x figure as a headline number rather than a working magnification. The useful range on an 80mm aperture is far lower, and pushing past it just makes the view dimmer and shakier.
Who this scope suits
Beginners who want to photograph the Moon and bright planets with a phone on their first or second night. The adapter and wireless shutter remove the usual barrier to a first astrophoto attempt.
It is a solid gift pick too, since the carry bag and no-tool setup make it forgiving in inexperienced hands.
Who should look elsewhere
Anyone chasing faint deep-sky objects should pass. Eighty millimetres is barely more light than a 70mm scope, and none of the reflector-class light grasp is there.
It is also the wrong tool if you live somewhere with a very short or unstable tripod already in mind, since the altazimuth stick mount wobbles at high power.
5. Celestron AstroMaster 70AZ – the highest-rated Celestron here
Celestron AstroMaster 70AZ Refractor Telescope for Moon & Planet Viewing
Aperture: 70mm
Focal length: 900mm
Mount: panhandle altazimuth
Weight: 10.8 pounds
Pros
- 900mm focal length boosts magnification
- Fully coated achromatic refractor
- Red dot finder needs no alignment
- Panhandle mount points smoothly
- Solid for Moon and planet work
Cons
- 70mm aperture limits faint targets
- No tracking motor for long sessions
- Heavier than most entry refractors
At 4.4 stars this is the highest-rated scope on the list, and it earns that score with one design choice: a 900mm focal length inside a 70mm tube. That is far longer than the 400mm typical of budget refractors.
Longer focal length means more magnification per eyepiece, so you reach useful planetary power without a Barlow. Jupiter’s moons, the Martian surface, and Saturn’s rings are all comfortably in range for a beginner.
The StarPointer red dot finder is another quiet win. It needs no collimation and aligns in seconds, which removes the single most common first-night stumbling block.
The panhandle altazimuth mount moves smoothly in all directions and doubles as a carry handle, so pointing at a target feels natural rather than fiddly. Reviewers call the Moon crisp and the planet detail satisfying for the class of scope.
The two-year warranty and included astronomy software make it a conventional Celestron package rather than a bare-bones import, and at 10.8 pounds it is sturdy rather than portable.
Who this scope suits
Planet-watchers and lunar observers who want maximum magnification per dollar without moving to a reflector. If your targets are Jupiter, Saturn, and the Moon, a 900mm focal length is worth more than extra aperture.
It is also a good choice for daytime birding and distant viewing thanks to the 90 degree erect image diagonal.
Who should look elsewhere
Deep-sky observers should skip it. A 70mm aperture simply does not gather enough light for nebulae or galaxies, and no eyepiece will change that physics.
Avoid it as well if you need to carry the scope to a dark site regularly. At 10.8 pounds plus a tripod it is a two-trip load.
6. Gskyer 600x90mm AZ Refractor – the widest aperture refractor
Gskyer Telescope 600x90mm AZ Astronomical Refractor Telescope for Adults
Aperture: 90mm
Focal length: 600mm
Mount: altazimuth tripod
Weight: 17.5 pounds
Pros
- 90mm is the widest refractor aperture here
- Three eyepieces plus a 3x Barlow
- Stainless steel tripod
- 48-degree erecting BAK7 prism
- Tool-free setup
Cons
- Tripod tops out near 49 inches
- Vibration at high magnification
- 17.5 pounds is heavy to carry
Ninety millimetres is as much aperture as you will find in a refractor under this ceiling, and that is what sets this Gskyer apart from every other lens scope here. Owners report clear views of the Moon, Jupiter with its moons, and Saturn.
Three eyepieces at 24x, 60x and 120x come in the box along with a 3x Barlow, so you have a wide spread of magnification without buying anything else. The stainless steel tripod is also the most solidly built stand in this group.
At about f/6.7 the focal ratio sits in a useful middle ground, and the 48-degree erecting BAK7 prism gives you an upright image for daytime terrestrial viewing, which is rarer than it should be at this budget.
The most repeated complaint is the tripod. It adjusts from roughly 31.5 to 49 inches, which means taller users crouch, and the finder sits low when the tube points skyward.
Several buyers solve this themselves by remounting the tube on a taller photography tripod. Vibration at high magnification on the supplied stand is the second most common note.
Who this scope suits
Adults who want a refractor with real aperture and care about build quality. It is a sensible choice for daytime wildlife and landscape viewing thanks to the upright prism and the steel tripod.
It also works as a shared family scope where two adults of different heights take turns, since the altazimuth mount adjusts smoothly.
Who should look elsewhere
Skip it if your priority is deep sky. A 90mm lens cannot compete with a 127mm mirror, and the aperture gap shows up immediately on nebulae.
It is also a poor travel choice at 17.5 pounds, and there is no carry bag in the box, which the shorter scopes here do include.
7. Gskyer 130EQ Reflector – manual tracking on a 5.1-inch mirror
Gskyer 130EQ Professional Astronomical Reflector Telescope
Aperture: 130mm
Focal length: 650mm at f/5
Mount: equatorial
Tube length: 24 inches
Pros
- 5.1 inch mirror gathers strong light
- German equatorial mount tracks manually
- Short 24 inch tube is easy to set up
- Bluetooth remote works without an app
- Three eyepieces and a 3x Barlow
Cons
- 30.1 pounds is hard to move
- Newtonian mirrors need collimation
- Polar alignment required before tracking
A 130mm mirror is the best compromise point in this whole group, and the Gskyer 130EQ is where you find it at the lowest weight of any 5-inch option listed. The 650mm focal length gives a fast f/5 ratio, which means brighter images at low power.
Owners emphasise two things in equal measure: the light grasp of the mirror, and how smoothly the equatorial mount tracks once it is aligned. On deep-sky targets, that combination makes long sessions possible.
The toothless focusing base and 24-inch optical tube simplify setup noticeably compared with longer tubes, and the Bluetooth camera remote pairs with iPhone and Android without needing an app.
The fast f/5 ratio does bring wide-field views, so clusters and nebulae sit comfortably in frame. It is also a digging scope, which many beginners underrate.
The weight is the real drawback at 30.1 pounds. That is a two-person carry, and it is the most common practical complaint in the reviews.
As with any Newtonian, collimation comes up repeatedly. The equatorial mount also has to be polar aligned before tracking behaves, and that alignment is the steepest part of setup.
Who this scope suits
Serious beginners who want to see galaxies, globular clusters, and bright nebulae from a backyard or dark site, and who are willing to spend an evening learning the mount. Our reflector telescope roundup covers the design in more detail.
It also suits someone whose observing site is set up once and used often, since the weight only matters when you move it.
Who should look elsewhere
Not for anyone who has to carry gear to a field or a mountaintop, or for a family sharing one small scope across different schedules. Thirty pounds is a commitment.
It is also the wrong first telescope for a person who wants to be pointing at objects within five minutes of opening the box.
8. MEEZAA 150EQ Reflector – the biggest mirror in the group
MEEZAA Telescope, 150EQ Newtonian Reflector Telescope for Adults Astronomy Beginners, Professional Astronomical Telescopes with Equatorial Mount, Tripod, Phone Adapter, Moon Filter and Large Carry Bag
Aperture: 150mm
Focal length: 650mm
Mount: German equatorial
Magnification: 26x to 130x
Pros
- 150mm mirror is the largest in this group
- Precision dials and slow-motion knobs
- Large accessory bundle
- Stainless steel tripod with tray
- Carry bag fits the whole kit
Cons
- Assembly takes real effort
- Heavy and awkward for one person
- Kellner eyepieces worth upgrading
This 150mm reflector collects the most light of anything on the list, and it does so on a German equatorial mount with precision dials and slow-motion knobs for smooth manual tracking. On faint deep-sky objects that extra aperture is visible.
Accessory completeness is the standout. You get a moon filter, a 2x Barlow, a red dot finder, and a phone adapter, plus a stainless steel tripod with a built-in accessory tray and a carry bag that swallows the whole kit.
At 4.4 stars with the highest five-star share among the equatorial reflectors here, owners consistently single out that completeness and the mount stability for the money.
Be realistic about assembly. Multiple reviewers describe it as complex with many small parts, and it takes noticeably longer to build than the altazimuth scopes on this list.
The included Kellner eyepieces are entry-level and are the first thing most owners upgrade. Several also report that swapping eyepieces knocks the target out of focus and forces a re-find.
One recurring complaint is worth flagging honestly: some buyers feel the effective aperture looks smaller than the advertised 150mm. Expect to judge the view rather than the number.
Who this scope suits
Observers who have already had a 70mm refractor and hit its ceiling, or who live under dark skies and want the most starlight per dollar. It is also attractive as a family scope that will not be outgrown quickly.
The carry bag makes it more mobile than the weight suggests, provided you have a car rather than a backpack.
Who should look elsewhere
Complete beginners who want a ten-minute setup should skip it. The assembly complexity is the most common reason buyers regret this one.
It is also the wrong pick for a small apartment balcony observer who has to carry the whole rig up stairs every clear night.
9. Dianfan 150EQ Reflector – pre-assembled equatorial head
Dianfan 150EQ Professional Astronomy Telescope for Adults High Powered
Aperture: 150mm
Focal length: 650mm
Mount: pre-assembled EQ
Dawes limit: 0.77 arc sec
Pros
- 150mm aperture for bright images
- Pre-assembled EQ mount sets up in 20 minutes
- Red dot finder and moon filter
- Custom carry bag
- Stainless steel tripod to 66 inches
Cons
- Newtonian mirrors need periodic collimation
- Kellner eyepieces are basic
- Polar alignment required for tracking
The Dianfan 150EQ solves the exact problem that makes the MEEZAA frustrating: it ships with a pre-assembled German-style equatorial mount. Owners report roughly twenty minutes from unpacking to first view.
Optically it is the same class: a 150mm mirror with a 650mm focal length, fully coated, giving 26x to 130x with the two included eyepieces and a 2x Barlow. The published Dawes limit of 0.77 arc seconds is respectable for the price class.
The tripod is the other differentiator, adjusting from 48.4 to 66.2 inches. That is a genuinely tall, adult-height stand, and it solves the crouching problem that frustrates owners of shorter refractors.
Red dot finder, phone adapter, moon filter, and a custom carry bag measured to the tube round out the package, and buyers repeatedly call the kit complete for the money.
The same caveats apply as to every Newtonian here. Mirrors need periodic collimation, the Kellner eyepieces are basic enough to upgrade early, and the equatorial head still needs polar alignment before tracking is smooth.
One practical note: a Newtonian gives an inverted image, so daytime terrestrial views come out upside down. That is normal for the design, not a defect.
Who this scope suits
Beginners who want reflector-class light grasp without a punishing first build. The pre-assembled head removes the hardest hour of setup, which is where most first telescopes get abandoned.
Adults of average height and taller will appreciate the adjustable tripod more than almost any other feature, and the carry bag makes it practical to move.
Who should look elsewhere
If you want a colour-correct, high-contrast image of the Moon and planets, a reflector is the wrong tool. Refractors give cleaner views at moderate power.
Skip it also if you cannot commit to occasional collimation, since that is not optional with a Newtonian design.
10. EACONN 80mm Travel Refractor – the lightest grab-and-go option
Telescopes for Adults Astronomy, 80mm Aperture 600mm Refractor Telescope for Kids & Beginners, Compact and Portable Travel Telescopio with Backpack
Aperture: 80mm
Focal length: 600mm
Weight: 840 g
Mount: altazimuth gimbal
Pros
- 840g build packs into the backpack
- Multi-coated 80mm optics
- 30x to 66x with two Kellner eyepieces
- Crosshair finder plus dual-position phone adapter
- Two-year warranty
Cons
- Tripod is short for adults
- Altitude stick is stiff
- Finder pairing is not intuitive
At 840 grams this is the lightest scope on the list by a wide margin, and the backpack it ships with means a child can carry their own telescope to the garden gate.
The optics are an 80mm multi-coated refractor on a 600mm focal length, supplied with K20mm and K9mm eyepieces giving 30x to 66x. That is a modest magnification ceiling, but it is honest for an 80mm aperture.
At 4.3 stars across more than 2200 reviews, with 72 percent five-star ratings, the praise concentrates on portability, quick assembly, and sharp views of the Moon and Jupiter.
The most repeated complaint, by a wide margin, is that the tripod is sized for children rather than adults. Adults end up stooping, which is uncomfortable over a long session.
Buyers also mention a stiff altitude adjustment stick and a finder whose pairing and alignment is not immediately intuitive. The manual is described as somewhat vague, though video instructions are included.
Who this scope suits
Children aged roughly eight to twelve, and any adult who wants a scope they can carry to a field, a balcony, or a friend’s garden in one hand. The two-year warranty is a plus at this tier.
The dual-position phone adapter makes it easy for a young astronomer to take a first photo of the Moon, which keeps the hobby interesting.
Who should look elsewhere
Adults who want a long evening session should skip it. The short tripod and stiff controls will end the evening well before the sky does.
It is also not a deep-sky scope in any sense. At 66x maximum, everything beyond the Moon and the brightest planets is out of reach.
What 500 Dollars Buys and What It Does Not
Expectation setting saves a lot of disappointment. Under this ceiling you are buying real optics, a usable mount, and enough aperture to see structure on the Moon and the outer planets. You are not buying the experience that arrives with a two-thousand-dollar German equatorial mount.
You cannot buy motorized tracking on a large aperture. Every tracking option here is either manual slow-motion control on an equatorial head, or nothing at all. Budget scopes with GoTo at this tier spend a large share of the money on motors rather than glass, which is why so many experienced observers recommend skipping them.
You also cannot buy astrophotography beyond a phone snapshot of the Moon or a bright planet. Our astrophotography telescope guide covers what a real imaging setup requires, and it is a different price tier entirely. A tripod-mounted Newtonian with a manual head produces trailed, noisy frames no matter how good the mirror is.
Realistic targets for this budget are the Moon in detail, Jupiter with its moons and belts, Saturn’s rings, the Pleiades, the Orion Nebula, the Andromeda Galaxy, and several globular clusters. Saturn’s Cassini Division, Titan, and the spiral structure of the Whirlpool Galaxy are stretch goals that depend heavily on your sky.
One thing you should never point any of these at is the Sun without a certified solar filter. Proper solar viewing needs dedicated equipment, covered in our solar telescope guide. A telescope pointed at the Sun without a filter can cause instant and permanent eye damage.
How to Choose a Telescope Under 500
Four numbers decide almost everything: aperture, focal length, mount type, and what comes in the eyepiece box. Read them in that order and the jargon stops mattering.
1. Aperture is the one spec that decides what you see
Aperture is the diameter of the main lens or mirror, and it governs both light gathering and resolution. Light gathering scales with the square of the diameter, so a 150mm mirror collects about 4.6 times the light of a 70mm scope. That is the difference between seeing a galaxy and guessing where it is.
Here is roughly what each aperture step in this group delivers:
1. 70-80mm, the refractors on this list: bright Moon craters, Jupiter with its moons, Saturn’s rings, open clusters, and the brightest nebulae as fuzzy patches.
2. 90mm, the widest refractor here: noticeably brighter planetary images and the first hint of nebula structure, still no galaxies beyond the very brightest.
3. 127-130mm, the mid-size reflectors: this is the threshold where deep-sky observing becomes genuinely rewarding. Orion Nebula shape, Andromeda resolvable, globular clusters start to break apart into stars.
4. 150mm, the largest mirrors here: brighter images, more detail on faint targets, and the ability to split double stars that smaller scopes blur together.
A rough maximum useful magnification rule is about twice the aperture in millimetres, so a 130mm scope tops out around 260x before images become dim and mushy. Ignore advertised magnification claims that exceed that; the extra power adds no detail.
2. Refractor or reflector, decided by your targets
Refractors give you sealed, maintenance-free optics with high contrast and correct colour on the Moon and planets. They are the easier choice for a first scope and for daytime viewing. Their limit is aperture per dollar, which is why the widest refractor under this ceiling is 90mm.
Reflectors put every dollar toward aperture. A Newtonian gives you a bigger mirror for less money and shows more faint objects, at the cost of needing periodic mirror collimation and giving an inverted image. If deep sky is the goal, reflector wins; if the Moon and planets are the goal, refractor is cleaner.
Catadioptric scopes fold a long focal length into a short tube, and the single one commonly found under this ceiling is an entry-level Maksutov. They are compact and give pleasant planetary views, but you pay for the folded design in aperture.
3. Altazimuth or equatorial mount
An altazimuth mount, or AZ mount, moves left-right and up-down. It sets up in seconds, has almost no learning curve, and is why most of the scopes here are AZ. Its weakness is that objects drift out of view because the sky moves diagonally while the mount does not.
A German equatorial mount, or EQ mount, is aligned to the celestial pole and then tracks objects across the sky in one axis. Slow-motion controls let you follow a planet by hand, and a motor can be added later for tracking. The cost is setup time, backlash, and a steeper first-hour learning curve. Our computerized telescope guide covers where motors actually earn their cost.
For the first hour with a telescope, an AZ mount wins outright. If you already know how to polar align, the EQ scopes here open up faint targets that will not sit still on an AZ.
4. Focal length, focal ratio, and eyepieces
Focal length is the distance light travels inside the tube, and combined with aperture it gives the focal ratio. A short focal length like 400mm on a 70mm scope gives a wide, bright view suited to star fields. A long focal length like 1000mm on a 127mm scope concentrates light for planetary detail.
For beginners, a focal ratio between f/5 and f/8 is the sweet spot. Faster scopes show more in one eyepiece and are easier to use; much slower scopes are mostly a photographer’s concern.
Finally, look at the eyepieces in the box. Every scope here includes two or three, and scopes with a Barlow lens double your options instantly. The common mistake is judging a telescope on its optics while ignoring a 4mm eyepiece that renders everything faint and hard to hold steady. If leftover budget exists, a mid-range Plossl eyepiece is the single best upgrade you can make.
Frequently Asked Questions
What is the cheapest but best telescope?
The cheapest telescope worth buying is a 6-inch class reflector rather than a department-store refractor. Scopes in the 70-90mm range under 150 dollars look fine at first and disappoint within weeks, because 70mm lenses collect too little light. The cheapest-but-good choice is the mid-size 127mm reflector class, where aperture per dollar finally works in your favour. Buy the smallest aperture you can live with, never the smallest number on the page.
What is the best telescope to buy for the money?
The best telescope to buy for the money under 500 is the Celestron PowerSeeker 127EQ. Its 127mm mirror gathers roughly three times the light of a 70mm refractor for a fraction of the cost of an 8-inch Dobsonian, which is the single biggest visible upgrade available at this budget. Budget for an hour of mirror collimation before your first session.
What is the best telescope at the lowest price?
At the very bottom of the range, the Celestron Travel Scope 70mm and the Gskyer 70mm AZ refractor are the strongest cheap options. Both are fully coated 70mm refractors with two eyepieces and a carry bag, and both handle the Moon and Jupiter well. Compared with spending the full budget on a 150mm reflector, you trade away deep-sky capability for portability and a much smaller first purchase.
What are the top 5 telescopes?
1. Gskyer 70mm AZ Refractor, best all-round starter with the highest review count. 2. Celestron PowerSeeker 127EQ, most light per dollar at 127mm. 3. Celestron AstroMaster 70AZ, best for planets thanks to a 900mm focal length. 4. Gskyer 130EQ Reflector, best 5-inch with manual equatorial tracking. 5. MEEZAA 150EQ Reflector, largest mirror in the group at 150mm.
How much magnification is actually useful on these scopes?
Useful magnification tops out at roughly twice the aperture in millimetres, so a 70mm refractor is useful to about 140x and a 150mm reflector to about 300x. Beyond that the image only gets dimmer and shakier, not more detailed. Headline figures like 300x on an entry scope are marketing; buy for aperture instead.
Do I need a motorized telescope?
Not at this budget. Experienced observers on forums routinely advise skipping computerized mounts under 500 and buying a larger aperture instead, because the motors eat money that would buy a bigger mirror. A manually tracked equatorial mount on a 127mm or 150mm reflector will show you far more than a motorized 70mm refractor pointing automatically.
Final Verdict
After working through all ten, the best telescopes under 500 depend on what you plan to point at. The Gskyer 70mm AZ Refractor is the single telescope I would hand a friend, because it needs no tools, breaks down less often than anything else here, and carries the deepest well of owner feedback in the group.
For deep-sky light per dollar, take the Celestron PowerSeeker 127EQ. For planets, take the Celestron AstroMaster 70AZ and its 900mm focal length. For a family or a child, the Gskyer 70mm is the easiest introduction, and the EACONN 80mm fits in a backpack. For travel, the Celestron Travel Scope 70mm packs complete.
Whichever you choose, buy the largest aperture you can carry to the sky and take it out on the first clear night. That habit is worth more than any feature on the spec sheet, and it is updated for 2026.
