Most telescope shopping guides start with magnification, and that is exactly how first-time buyers end up disappointed. A scope advertised at 675x with a plastic 3mm eyepiece will show you a blurry smear of Jupiter and a shaky image of the Moon, while a 130mm reflector with no electronics at all will show you craters, cloud belts and Saturn’s rings. Aperture wins. It always has.
That is the filter we applied to every telescope in this guide to the best telescopes under 500 dollars. We looked past listed power figures, counted the actual glass in millimeters, checked what the mount can hold steady, and read what owners say after a few months rather than on day one. Every scope below sits inside the same 500 dollar budget, so the only real question is how much light you get for it and how fussy the setup is.
What you will find here: eight scopes covering achromatic refractors, Newtonian reflectors on equatorial mounts, and a tabletop Dobsonian, plus a buying guide that explains collimation, chromatic aberration and the GoTo-versus-manual argument before you spend anything. If you are shopping for a younger or newer observer, our kids telescope guide covers the simpler end of the market, and if your interest leans toward computerized pointing, read our GoTo telescope picks instead.

1. Celestron AstroMaster 70AZ: Best Telescope Under 500 Dollars for Beginners
Celestron AstroMaster 70AZ Refractor Telescope for Moon & Planet Viewing
70mm coated achromatic refractor
900mm focal length
Altazimuth mount
10.8 pounds
+ The Good
- Needs no collimation and works straight out of the box
- Panhandle altazimuth mount is intuitive for first-time users
- Crisp lunar and planetary views from a long 900mm focal length
- Two-year limited warranty with support
- Tool-free assembly
- The Bad
- 70mm aperture keeps deep-sky targets dim
- No tracking so objects drift during long views
- 900mm focal length caps planetary magnification
- Basic steel tripod shows shake at high power
This is the telescope I hand to friends who tell me they want to look at the stars and have no idea where to start. A 70mm fully coated achromatic refractor with a 900mm focal length needs no collimation, no polar alignment and no batteries. You screw it together, point it, and it works.
That simplicity is the whole argument. Refractor optics are sealed, so nothing inside needs adjusting, which means the one task that trips up most first-time buyers simply does not exist here. The 900mm focal length also makes it a genuinely useful planetary scope, since long focal length is what lets you push magnification without the image falling apart.
The panhandle altazimuth mount is the other quiet win. It takes about a minute to aim with two hands, and once the target is near the eyepiece, fine adjustments with a slow-motion style thumbwheel are easy. A StarPointer red dot finder comes in the box, which is faster to align than a traditional finderscope and shows you a field of stars rather than a tiny circle.
Owners rate this at 4.4 across 3790 reviews, and the praise is unusually consistent: no collimation, quick setup, and clean views of the Moon at any time of the month. The complaints are all about the same limitation, the aperture, and one about the tripod shaking at high power.
What you will actually see with the 70AZ
The Moon is where this scope earns its keep. Craters along the terminator and craters in shadow during the quarter phases all come through clearly, and because the Moon is bright, aperture is not the limiting factor here.
Jupiter shows its four Galilean moons as points of light and shows banding with a 10mm eyepiece. Saturn is the harder target, and at 70mm you will see the rings as a shape rather than as Cassini Division detail.
Deep-sky is where the 70mm aperture bites. The Orion Nebula shows as a fuzzy patch, the Pleiades resolve into a cluster of individual stars, and Andromeda is a small smudge. That is normal and not a defect, it is physics, and it is exactly the reason the next step up exists.
Who should skip it and why
Skip this one if galaxies and nebulae are the reason you are buying a telescope. A 130mm reflector collects roughly 3.5 times the light of a 70mm refractor, and that difference shows up on every faint target. It is also not built for astrophotography beyond phone snapshots, and the steel tripod transmits vibration at the magnifications where planetary detail lives.
Do buy it if you want a reliable, low-fuss first instrument that shows the Moon and the planets well, or if the buyer is a child learning the sky. In our experience it is the lowest-failure path into astronomy, because there is nothing in the optical train that can be knocked out of alignment in transit.
2. Celestron AstroMaster 130EQ: Best Telescope Under 500 Dollars for Deep-Sky Viewing
Celestron AstroMaster 130EQ Telescope for Deep-Sky Beginners
130mm coated Newtonian reflector
650mm focal length
German equatorial mount
17 pounds
+ The Good
- 130mm aperture gives a big brightness jump in a package you can still carry
- German equatorial mount with dual slow-motion knobs
- Bright deep-sky views including galaxies and nebulae
- Two-year limited warranty
- Tool-free assembly with clear instructions
- The Bad
- Newtonian optics need collimation and a laser collimator
- Light steel tripod legs feel shaky when extended
- 17 pounds is heavy and awkward to move
- Red dot finder alignment is hard to fine-tune
If your list of targets includes anything beyond the Moon and planets, this is the scope. A 130mm mirror collects roughly 2.1 times the light of a 90mm refractor and about 3.5 times that of a 70mm, and that is the difference between seeing a galaxy as a smudge and seeing spiral structure in it.
The German equatorial mount is the part that surprises people. Its two slow-motion cables let you nudge the scope in each axis while your eye stays at the eyepiece, which is a slow, controlled way to center a target that a simple altazimuth handle cannot offer. You do need to set the polar angle once, and getting that right is the main skill this scope teaches.
Owner reviews average 4.3 from 3444 ratings, and the recurring theme is value. Once the mirrors are aligned, the consensus is that the images are sharper than owners expected for the money, and that the mount’s slow-motion controls make centering fussy targets manageable.
Several reviewers also recommend adding a Barlow and better eyepieces as the first upgrade.
The learning curve is real, though. A Newtonian needs its two mirrors aligned with each other and with the focuser, and if it arrives out of alignment, the first few sessions can be confusing. Budget an evening for collimation and a laser collimator, and treat that as part of buying a Newtonian rather than a fault in it.
What 130mm of aperture actually shows you
At 130mm, the Messier catalog stops being abstract. The Orion Nebula shows structure, the Andromeda Galaxy shows a core and dust lanes with averted vision, and globular clusters in M13 and M15 begin to resolve into individual stars at the edges.
Saturn gains a visible Cassini Division at good seeing, and Jupiter shows the Great Red Spot as a spot rather than a smudge.
The published resolution figure for this scope is 0.89 arc seconds, which is well beyond what the atmosphere typically allows, so seeing rather than optics will be your limiting factor on most nights. Expect excellent results on steady nights above a thermal horizon and soft images on nights when the air is turbulent.
Consider the trade-offs before you buy
At 17 pounds assembled this is a two-person carry, and the light steel tripod is the weak point in the package. Shaking is most annoying at the high magnification you would use on the planets, so if planetary detail is your main interest rather than deep-sky, look at the 127mm PowerSeeker further down instead.
And do not buy this for long-exposure astrophotography, since a German equatorial mount with slow-motion cables cannot track accurately enough for tracked deep-sky images.
3. Gskyer 70mm AZ Refractor: Best Value Telescope Under 500 Dollars
Gskyer Telescope, 70mm Aperture 400mm AZ Mount Astronomical Refracting Telescope for Kids Beginners – Travel Telescope with Carry Bag, Phone Adapter and Wireless Remote.
70mm fully coated objective
400mm focal length
altazimuth tripod mount
One-year warranty
+ The Good
- Largest review base in this guide at over 22000 ratings
- Two eyepieces plus a 3x Barlow included
- Smartphone adapter and wireless remote for photos
- Carry bag and adjustable tripod suit travel and storage
- Ready to use with no collimation
- The Bad
- 70mm aperture is the smallest here
- 400mm focal length gives low magnification on planets
- Manual altazimuth means constant re-aiming as targets drift
- Light duty mount and tripod amplify bumps
With 22081 ratings averaging 4.3, this is the most thoroughly reviewed telescope in the list, and that volume of owner feedback is itself useful information. The consensus is remarkably stable: it is an easy, inexpensive grab-and-go instrument that produces bright, sharp lunar views and a generous accessory bundle for the money.
The 70mm objective is fully coated at a 400mm focal length, giving a compact tube at roughly 40cm long. Two replaceable eyepieces and a 3x Barlow lens are included, so you have a low-power wide view and a higher-power option without buying anything.
A 5×24 reflex finder with cross-hairs handles target location, and the whole thing breaks down into a carry bag.
What makes it interesting is the smartphone adapter and wireless camera remote. Neither produces astrophotography in any deep sense, but both let you capture the Moon and bright planets from a tripod-mounted phone, which is a genuinely good way to get a new observer excited about the hobby before they learn imaging.
The forum consensus on scopes like this is worth repeating, because it is the single most common buying mistake: listed magnification on budget listings is marketing, not a specification you should shop by. The 120x figure printed for this scope is not a real observing mode.
Useful magnification is roughly twice the aperture in millimeters, so 140x is the practical ceiling here, and pushing past it produces a dim hollow image rather than more detail.
Where this scope beats its rivals
Against the other budget refractor, the difference is accessories and simplicity. A longer-focal-length budget refractor gives better planetary views because magnification scales with focal length, but this package gives you a phone adapter, a wireless remote and a bag at no extra cost.
For a kid, a traveler, or anyone who wants to point at the sky from a balcony, those three things matter more than planetary resolution.
Owners also highlight how quickly it comes together and how well it survives being carried around in a car. That robustness is why it appears in our kids telescope guide as well.
Where it falls short
A 400mm focal length is short, and that is the honest limitation. On Jupiter you will see the moons and maybe the belt structure, and on Saturn the rings will be small. Aperture also caps deep-sky work, so treat any list of faint galaxies as out of reach.
The altazimuth mount has no tracking, so during a long look at Jupiter the target will drift steadily out of the field. That is the main reason experienced forum users steer new buyers toward larger manual scopes.
4. Celestron PowerSeeker 127EQ: Best Telescope Under 500 Dollars for Planets
Celestron PowerSeeker 127EQ Reflector Telescope for Home Astronomy
127mm coated Newtonian reflector
1000mm focal length
German equatorial mount
13 pounds
+ The Good
- 1000mm focal length is the longest here and suits planetary magnification
- Coated aluminum and SiO2 mirrors
- 13 pounds suits carrying between backyards and campsites
- Includes 20mm and 4mm eyepieces plus a 3x Barlow
- Two-year warranty with support
- The Bad
- Newtonian optics need collimation and often arrive out of alignment
- Plastic parts in the equatorial mount feel imprecise
- Light tripod shakes at high power
- The 4mm eyepiece is impractical to look through
- Weak finder with a reversed image
This is the scope to buy if Saturn and Jupiter are the targets. At 1000mm focal length, the PowerSeeker 127EQ is the longest optical tube in this guide, and focal length is what determines how much magnification you can use before the image turns to mush. It also carries a 127mm mirror, so it is not a lightweight-planet rig in aperture terms.
Owners rate it 4.1 across 9247 reviews, and the pattern in those reviews is value with caveats. Many describe strong views of Saturn, Jupiter and the Moon once the mirrors are collimated.
The most repeated criticism is not optical quality, it is the included accessories: the 4mm eyepiece exceeds what the scope can support usefully, the 3x Barlow is mediocre, and the finder is weak with a reversed image.
That is fixable for very little money. Replace the 4mm with a 9mm or 15mm Plossl, ignore the finder or replace it, and the scope transforms. It is one of the more common upgrade paths forum regulars recommend, and it costs a fraction of buying a new telescope.
At 13 pounds this is also one of the most genuinely portable reflectors here. It moves between a backyard, a campsite and a dark-sky site without feeling like a heavy piece of furniture, which matters more than people expect for a telescope you have to set up in the dark.
What the 1000mm focal length buys you
Planetary detail. At 1000mm focal length you can realistically use 250x to 300x on a steady night, which is enough magnification to show Saturn’s ring structure and the Cassini Division in good conditions, and to hold Jupiter’s larger storms as discrete shapes. The published Dawes limit of 0.91 arc seconds tells you the optics are not the constraint, atmosphere is.
The trade-off is field of view. The stated field of view of 2.5 degrees is wide enough for the Moon and for larger clusters but too narrow for sweeping big deep-sky fields, and the 0.91 arc second figure means galaxies will show as cores rather than as resolved objects. This is a planet-first instrument.
Who should pass on it
If you have never collimated a Newtonian, this is not the gentle place to start. The consensus in beginner forum threads is consistent that a reflector arriving out of alignment, with a manual that does not explain the process, can cost an evening and some patience.
A refractor like the AstroMaster 70AZ has no such step. If you do want this one, buy a collimation cap and a laser collimator, and expect the first session to be a workshop.
5. Sky-Watcher Heritage 150 Tabletop Dobsonian: Best Telescope Under 500 Dollars for Big Aperture
Sky-Watcher Heritage 150 Tabletop Dobsonian Telescope – Perfect for Beginners, Easy Setup, Portable, and Fun (S11710)
150mm parabolic primary mirror
750mm focal length at f/5
Collapsible tabletop design
23 pounds
+ The Good
- 150mm aperture is the largest in this guide
- Fast f/5 ratio gives wide and bright deep-sky fields
- Parabolic borosilicate mirror with RAQ reflective coating
- Collapsible tube stores easily and holds collimation
- Tabletop design with rubber feet cuts vibration
- No alignment procedure and a two-year warranty
- The Bad
- Comes with no eyepieces so plan on buying those first
- Needs a table or stand at a comfortable viewing height
- The 23 pound base is heavy and awkward
- Newtonian design still needs occasional collimation
This is the largest aperture in the guide, and that is the entire argument. A 150mm mirror collects roughly 4.5 times the light of a 70mm refractor, which is why experienced forum users treat a Dobsonian as the aperture-per-dollar benchmark in this price band.
On a night of steady seeing under a dark sky, nothing else here comes close to what it reveals on faint targets.
The Heritage 150 is also the least complicated telescope in the list. A Dobsonian mount is a box that rotates in altitude and azimuth, with no polar alignment, no gears to adjust and no equatorial wedge to level.
Point it, look, adjust. Reviewers describe it as the easiest and most capable starter Dobsonian, and 104 owners rate it 4.2.
Two design details matter more than they sound. The f/5 focal ratio gives a wide bright field, so galaxies and nebulae sit comfortably in view rather than needing constant re-centering.
The collapsible tube also stores in a much smaller footprint than a full-length Dobsonian while retaining collimation, which solves the storage problem that pushes people away from tabletop scopes.
It comes without eyepieces. That is not a defect, it is how the category is built, but it means your real cost is the scope plus two or three eyepieces. Budget for a 25mm or 26mm for the widest views and a 10mm for detail before you buy anything else.
What 150mm shows that the others cannot
From a suburban backyard, a 150mm shows the Orion Nebula with visible wings, the Andromeda Galaxy with a bright core and surrounding dust, and the Hercules and M13 globular clusters partially resolved.
You will also see the Ring and Dumbbell nebulae as obvious non-star objects, plus dozens of Messier objects that 70mm scopes leave invisible. Saturn gains visible ring separation on good nights, which is where the fast f/5 ratio stops being an advantage, because long focal ratios favor planets and short ones favor deep sky.
The limitation is portability. At 23 pounds, this is a scope you set up in one place. It also needs a surface at a comfortable viewing height, which rules it out for casual use in a chair on a balcony.
Who should buy something else
Buy a refractor instead if you want something that works on a table outdoors, fits in a car easily, or has zero maintenance. The Heritage 150 collides with walls and requires a stand.
The forum guidance is that a tabletop Dobsonian is a great entry choice, and we agree, provided you have somewhere to put it.
6. Gskyer 130EQ: Best Telescope Under 500 Dollars for a Compact Setup
Gskyer 130EQ Professional Astronomical Reflector Telescope
130mm multi-coated reflector
650mm focal length at f/5
German equatorial EQ-130 mount
30.1 pounds
+ The Good
- 130mm aperture with bright
- contrasty images
- Fast f/5 ratio and a 24 inch tube for quick setup
- Toothless focusing base is smooth and beginner friendly
- German equatorial mount supports precise tracking
- Three eyepieces plus a 3x Barlow and finder included
- Top rating in this guide at 4.4
- The Bad
- Assembled weight of 30.1 pounds is heavy to carry
- Newtonian still needs occasional collimation after transport
- Published magnification ratings are optimistic
- Wireless remote depends on phone Bluetooth rather than an app
This scope ties for the highest rating in the guide at 4.4, and its distinguishing feature is physical. A 24 inch optical tube on a German equatorial mount packs 130mm of aperture into a package that is meaningfully shorter than the other 130mm options here.
That makes it the one to pick if you need to carry a real telescope between rooms or to a site.
Owners single out the toothless focusing base, which uses an internal friction mechanism instead of the usual toothed rack and pinion. In practice it means focusing is smooth and does not rack back out of position, which removes one of the most common irritations on budget reflectors.
The German equatorial mount gives more precise tracking than a simple altazimuth, and the f/5 ratio keeps fields bright and wide.
The accessory package is unusually full: three eyepieces, a 3x Barlow lens, a finderscope, an adjustable tripod and a Bluetooth wireless camera remote that works with iPhone and Android. Reviewers consistently call that bundle good value, particularly for a scope in this class.
The catch is weight. At 30.1 pounds assembled this is the heaviest package in the guide, and that is a real consideration if you plan to move it. The other honest note is the published 307x maximum magnification, which is a listing figure rather than an observing mode, so treat the practical ceiling as roughly 260x for a 130mm scope.
Why the short tube matters
Length is the quiet factor in reflector performance. A shorter tube at the same aperture means a wider field of view and a brighter flatter view of deep-sky objects, and it means the whole assembly fits through a doorway and into a car without disassembly.
For anyone setting up outside in the dark, fewer assembly steps is worth a lot.
The wide field also makes star-hopping easier, because more stars are visible at once and you can use them to walk to your target. That is a real skill advantage over narrower scopes.
Where the weight argument cuts the other way
If your observing plan is a balcony, a patio table or a camping trip, 30.1 pounds is the wrong number. A tabletop Dobsonian or a small refractor is the more sensible choice.
This scope is for someone who has a designated observing spot and wants the most aperture they can carry once. The 4.4 rating from 454 owners says the optics and focusing are excellent, so the decision is purely about portability.
7. SOLOMARK 130EQ: Best Telescope Under 500 Dollars for Included Accessories
Telescope 130EQ Newtonian Reflector Telescopes for Adults, Professional Telescopes for Adults Astronomy, Comes with 1.5X Barlow Lens Smartphone Adapter & 13% T Moon Filter
130mm fully coated reflector
650mm focal length
Equatorial mount with slow-motion cables
Moon filter included
+ The Good
- 130mm aperture for brighter planetary and lunar detail
- German equatorial mount with dials and slow-motion cables
- Bundle includes two eyepieces plus a 1.5x Barlow plus a moon filter and phone adapter
- Carbon-fiber style tube is lighter than metal
- Large aluminum tripod with accessory tray
- Ten pieces in the box
- The Bad
- Included finder is cheap plastic and hard to align
- Often arrives out of collimation with no guidance
- Main mirror lacks a center mark which makes collimation harder
- Tripod is still noticeable and the mount takes practice
- Listing describes Plossl eyepieces but Kellner eyepieces are included
This is the package deal of the list. A 130mm Newtonian on a German equatorial mount arrives with two eyepieces, a 1.5x erecting Barlow, a 1.25 inch 13% transmission moon filter, a cellphone adapter, a straight-through finder and an accessory tray.
That is ten pieces in the box, and very few scopes in this aperture class include a moon filter as standard.
Owners rate it 4.2 from 1360 reviews, and what they like most is the completeness. Several mention the light carbon-fiber style tube, which looks modern and weighs less than a metal tube of the same size.
The large aluminum tripod with a tray is also called out as more stable than the light steel tripods on the Celestron scopes here.
The criticism is specific and worth weighing. The included finder is the most commonly criticized component across the reviews, described as cheap plastic that is hard to align.
More seriously, the scope frequently arrives out of collimation, the main mirror has no center mark to make alignment easier, and the manual does not explain the collimation process, so several owners had to buy a collimation tool and learn the process themselves.
There is also a listing mismatch worth flagging: the product description refers to Plossl eyepieces while buyers report receiving Kellner eyepieces. If eyepiece quality matters to you, replace them rather than relying on the description.
Is the moon filter worth anything?
Yes, for beginners it is more useful than most people expect. The included filter cuts lunar brightness so the surface detail stays visible instead of glaring, which matters on nights when the Moon is near full.
It also reduces the sense of a shimmering overexposed disc and makes crater detail easier to pick out on the terminator.
It does nothing for planets or deep-sky objects, and it is a screw-in filter, so check that it matches your eyepiece thread size before assuming it will fit anything you add later.
Who should consider a different scope
If you want a worry-free purchase with no adjustment, buy the refractor instead. A Newtonian that arrives misaligned with a manual that does not explain it is a poor match for someone who expects to unpack and observe.
If you already own a 25mm and a 10mm and have a collimation cap, this package is arguably the best value per dollar here. If you own nothing, plan the first session around setup rather than around observing.
8. Koolpte 80mm: Best Telescope Under 500 Dollars for Phone Photos
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.
80mm multi-coated objective
600mm focal length at f/6.7
Altazimuth tripod
Carry bag included
+ The Good
- Fully multi-coated high transmission optics for a bright
- sharp image
- No-tool assembly gets beginners observing quickly
- Phone adapter and wireless remote simplify phone astrophotography
- Carrying bag and adjustable tripod make it easy to transport
- 25mm and 10mm eyepieces plus a 3x Barlow cover lunar use
- The Bad
- 80mm aperture limits light gathering for faint deep-sky targets
- Manual altazimuth has no tracking so targets drift out of view
- Bundled eyepieces are entry level and usually replaced soon
- Basic build quality on the mount and tripod
Among the budget refractors, the Koolpte 80mm has the strongest coating specification. Fully multi-coated high transmission glass at 80mm aperture and 600mm focal length is a better coating than the 70mm budget lenses, and the 600mm focal length gives more magnification per eyepiece than the 400mm tube in pick three.
Owners rate it 4.3 from 3972 reviews, and the praised features are consistent: a bright, sharp image, tool-free assembly, and a bundle that includes a phone adapter, a wireless remote and a carry bag. The stated limitation in nearly every review is the same, aperture size, which keeps deep-sky results modest.
The 25mm and 10mm eyepieces give 24x and 60x, and adding the 3x Barlow takes that to 180x on the Moon, which is a sensible pairing for a scope in this class.
The 5×24 finder handles target location, and no-tool assembly means you can set it up in a few minutes in daylight and be observing the same night.
As with the other altazimuth scopes here, there is no tracking, so anything you look at drifts out of frame. That is manageable for the Moon and planets, where you re-center constantly anyway, and awkward for deep sky.
What 80mm versus 70mm actually changes
The step from 70mm to 80mm looks small on paper but is not. Light gathering scales with the square of the aperture, so 80mm collects about 30% more light than 70mm, and that is the difference between a faint smudge and a recognizable object on targets like the Andromeda Galaxy.
Add the extra 200mm of focal length and you also get more magnification from the same eyepieces, which is why this scope holds up better on Jupiter than the 400mm tube in pick three.
It still does not reach reflector territory, and it is still a compromise against a 130mm Newtonian. As a grab-and-go refractor, it is the best-balanced of the budget lenses in this guide.
When to spend elsewhere instead
If deep-sky objects are your goal, put the money into aperture rather than coatings. A 130mm reflector shows more of the sky than any refractor at this level, and coatings mainly improve brightness slightly.
If your interest is purely planets, save the difference and get a refractor with a longer focal length instead. This scope is the right call for someone who wants a complete low-maintenance package they can carry outside on a whim.
How We Picked the Telescopes in This List
Aperture first. We sorted every scope by the diameter of its main lens or mirror, because light-gathering power scales with the square of that number and nothing else on the spec sheet changes what you can actually see.
A 130mm reflector beats a 70mm refractor on every faint target, regardless of which one lists a higher magnification.
Owner feedback second. We weighted review volume and consistency heavily. The Gskyer 70mm has more than 22000 ratings and the PowerSeeker 127EQ has more than 9000, which means the praise and the complaints in those reviews are patterns rather than anecdotes.
Where a scope had few reviews, we weighted the specification and said so in the review itself.
Optical design and maintenance third. We favored scopes that work without adjustment for absolute beginners, but we did not skip reflectors, because aperture is the dominant variable at this budget.
Every Newtonian here is a legitimate choice for someone willing to collimate once.
Accessories last. We noted what each package includes, because a supplied 4mm eyepiece, a weak finder and a plastic red dot all affect the first night. We never used listed magnification ratings to rank anything.
Aperture, Focal Length and Focal Ratio: The Three Numbers That Matter
Aperture is the diameter of the main lens or primary mirror, measured in millimeters. It controls light gathering and resolution, and it is the number that decides what a telescope can show.
Light-gathering power scales with the square of the aperture, so a 150mm scope collects roughly 4.5 times the light of a 70mm one.
Focal length is the distance from the lens to the focus, also in millimeters. Longer focal length means more magnification from any given eyepiece, which is why a 1000mm Newtonian is a planet scope and a 400mm refractor is a wide-field Moon scope.
Focal ratio is focal length divided by aperture, written as f/5 or f/13, and it describes how wide the field of view is.
Useful magnification is roughly twice the aperture in millimeters. A 70mm refractor stays at 140x, and a 130mm scope at about 260x. Every listing you see advertising 500x or 675x on a small scope is quoting a number no observer will ever use.
Buyers who chase those figures end up with dim and color-fringed images instead of more detail.
One more optical term is worth knowing before you read the reviews. Chromatic aberration is the colored fringing you get around high-contrast objects from cheap achromatic refractors, and it becomes obvious on bright targets like the Moon or Venus once you pass roughly 100x. Reflectors do not have this problem because there is no glass element doing the focusing.
Our optics buying guides cover the same trade-offs in more depth for other categories.
Refractor vs Reflector vs Dobsonian: Which Design Fits How You Observe
A refractor uses a glass lens. It needs no collimation, gives high contrast and shows sharp planetary detail, but aperture is expensive per millimeter, so budget refractors top out around 80mm.
Choose one if you want zero maintenance and immediate results.
A Newtonian reflector uses a concave primary mirror with a secondary that deflects the image to the side. It gives far more aperture per dollar, which is why every serious deep-sky option in this guide is a Newtonian. The cost is a collimation routine and a reversed image.
A Dobsonian is a Newtonian on the simplest mount ever designed, a rotating box. It is the most aperture you can buy for the money and the least fiddly to use, but you supply the eyepieces and you need a table or stand.
GoTo vs Manual Telescopes at This Budget
None of the telescopes in this guide is GoTo, and that is a deliberate decision rather than a gap. At this budget, the same money spent on automation is money taken away from aperture.
The consensus in telescope forums is blunt about the trade: a manual 150mm Dobsonian will show you far more than a computerized 90mm scope, and the motorized version often needs a fresh alignment routine every night before it points correctly.
The other argument for going manual is the skill it teaches. Star-hopping sounds intimidating and becomes second nature within a few sessions.
It also removes your dependence on batteries, firmware and alignment success. If you want automation, read our GoTo telescope guide to see what that capability costs at higher budgets.
How to Tell if Your Telescope Needs Collimation
Reflectors arrive out of alignment more often than buyers expect, and the symptom is easy to recognize. If a star looks like a donut or a faint cross rather than a point, the mirrors are misaligned.
A cheap collimation cap costs little and saves an evening of guessing.
The procedure runs in four steps. First, set the telescope level and aim it at a bright, evenly lit surface such as a white wall. Second, look through the focuser and adjust the primary mirror cell until the reflection of the secondary is centered in the field.
Third, adjust the secondary mirror until its reflection is concentric with the primary. Fourth, repeat the primary adjustment until the reflection of your eye sits centered in the reflection of the secondary.
Check collimation again after any transport, since a knocked tube is the most common reason a well-aligned scope suddenly looks soft. It takes five minutes.
Astrophotography With a 500 Dollar Telescope: What to Expect
Phone adapters and wireless remotes, which appear in three of the picks here, are for the Moon and bright planets only. Hold the phone to the eyepiece, tap focus, and you get a recognizable image of a cratered Moon.
Long-exposure deep-sky astrophotography is a different discipline, and none of these scopes is built for it. A German equatorial mount with slow-motion cables cannot hold tracking accurately enough for a minute-plus exposure, and untracked single frames produce trailed stars.
What you can attempt is short high-frame-rate video of the Moon and planets, where a frame captured thousands of times and stacked resolves more detail than the eye can see. Everything deeper needs a mount and a scope above this budget.
What to Buy With the Rest of Your Telescope Budget
Eyepieces are the highest-value upgrade for a reflector, and the cheapest scopes here come with the worst ones. A 4mm eyepiece on a 70mm or 127mm scope exceeds the useful magnification ceiling and gives almost no eye relief, which is why owners complain about it.
Replacing a 4mm with a 9mm or 15mm Plossl typically improves the view more than any other purchase.
A modest 2x Barlow is the second-best spend. Most of these scopes come with a 3x, which pushes you past what the aperture supports, so a 2x lets you fill the gap between eyepieces without overshooting.
A red dot finder and a collimation cap complete the kit for a Newtonian, and a moon filter helps if the Moon is your main target.
If the Sky-Watcher Heritage 150 is the scope you choose, eyepieces are not optional. Nothing comes in the box, so a 25mm or 26mm for wide views plus a 10mm for detail is your starting pair, and the rest of the budget can wait.
Frequently Asked Questions
What is the best telescope to buy for the money?
At this budget the Celestron AstroMaster 70AZ is the most dependable first telescope, because a refractor needs no collimation and works immediately after assembly. If your targets include galaxies and nebulae, spend up to the Celestron AstroMaster 130EQ instead, since 130mm of aperture is where the real step in brightness happens. Buy on aperture, not on listed magnification, and buy the largest aperture you can carry.
How much should I spend on a beginner telescope?
Around 250 to 300 dollars is the practical floor for a first telescope that will not disappoint, which is the number telescope forum regulars give most often. Below that, you are choosing between a 70mm refractor and a 100mm reflector, and the difference is visible on every faint target. Spending up to 500 dollars gets you 130mm or even 150mm of aperture, which is the single largest jump in capability at this level.
What kind of telescope should I get as a beginner?
A reflector on a manual equatorial or Dobsonian mount gives you the most aperture per dollar, and aperture is what determines what you can see. A refractor is the low-maintenance choice with no collimation and sharper planetary views. A Dobsonian is the simplest to operate. A GoTo scope is convenient but costs aperture at this budget. For most beginners we would start with a reflector, provided you are willing to collimate it once.
Which telescopes suffer from chromatic aberration?
Budget achromatic refractors with short focal ratios show the most color fringing, and the effect becomes obvious above roughly 100x on bright targets like the Moon or Venus. The 70mm and 80mm refractors in this guide are the ones most likely to show it, especially the shorter 400mm focal length model. Reflectors do not suffer from this at all because no glass element does the focusing, and a longer-focal-length refractor reduces the visible fringing.
How to tell if your telescope needs collimation?
Look at a bright star at low power. If it appears as a donut or a faint cross instead of a point, or if the whole view looks hazy and low-contrast, the mirrors are misaligned. You can also check by aiming at a white wall in daylight and confirming the reflection of your eye is centered in the reflection of the secondary. A collimation cap makes the process much faster and is the first accessory we recommend buying.
Should I buy a GoTo telescope or a manual Dobsonian?
At this budget, a manual Dobsonian. A motorized GoTo mount costs you aperture, and the community consensus is that the extra light is worth more than computerized pointing. A manual scope also teaches star-hopping, which removes your dependence on batteries, firmware and successful alignment. GoTo capability is worth paying for at higher budgets, when the mount and optics are good enough that you are not trading away visible detail to get it.
Conclusion: The Best Telescopes Under 500 Dollars, Final Word
The Celestron AstroMaster 70AZ is our pick as the best telescope under 500 dollars for most people, because a refractor that needs no collimation removes the single most common reason first-time buyers give up in the first month.
The Celestron AstroMaster 130EQ is the choice if galaxies and nebulae matter to you, and the Sky-Watcher Heritage 150 shows the most of everything if you have somewhere solid to put it.
Whichever you pick, spend your decision on aperture rather than magnification, and treat the remaining budget as eyepieces and a collimation cap rather than as a second telescope.
