The best telescope under 500 dollars for a first purchase is the Celestron-adjacent Gskyer 70mm refractor: it has more than 22000 ratings, a stable-enough altazimuth tripod and a carry bag, so it survives being handed around a family. If your real goal is light, skip straight to the 150mm scopes further down.
Aperture is the spec that decides what you actually see, and the number printed on the box next to “600x power” means almost nothing on its own. A 70mm refractor and a 150mm reflector can advertise similar magnification figures while the reflector gathers roughly four times the light, which is the difference between a grey smudge and a recognisable galaxy.
We spent six weeks comparing the ten scopes below, checking the published aperture and focal length of each against what reviewers report seeing, and weighing the mounts, included eyepieces and finder scopes. This guide covers the best telescopes under 500 dollars across Dobsonian, altazimuth Newtonian, equatorial, refractor and smart-scope designs, so you can match a telescope to your targets instead of to a marketing claim.
One honest note before we start: nothing at this budget is a luxury instrument. A 500-dollar telescope will show you the Moon’s craters, Saturn’s rings, Jupiter’s four Galilean moons and a long list of deep-sky objects. It will not give you faint galaxies in a bright city sky, and it will not produce print-quality astrophotos. Every pick below sets that limit clearly.

1. Gskyer 70mm AZ Refractor – the Most Proven 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.
70mm aperture
400mm f/5.7
Fully coated optics
Altazimuth tripod
Phone adapter
Pros
- Over 22000 ratings averaging 4.3
- Sharp Moon and planetary views
- Quick beginner assembly
- Tube and tripod pack into the carry bag
Cons
- 70mm aperture is the smallest in this group
- 400mm focal length limits deep-sky reach
- Included eyepieces are entry level
This is the scope we recommend first for a family buying a first telescope, and the reason is not the optics. It is that more than 22000 people have rated it at 4.3 stars, which means every awkward part of the design has already been solved by someone else before you unbox it.
On the Moon, which is the first target anyone looks at, a 70mm fully coated refractor with a 400mm focal length at f/5.7 gives a clean, bright image with obvious craters along the terminator. Two eyepieces and a 3x Barlow lens are in the box, and the 5×24 cross-hair finder scope makes centring a target straightforward even for a first-timer.
The included phone adapter and wireless remote are the feature owners mention most. Screw the phone to the eyepiece, open the camera, and you can capture the Moon and bright planets on the first evening, which does more for a new owner’s confidence than any amount of magnification marketing.
Set-up is genuinely quick: assemble the tripod, attach the tube, centre the finder, done. The whole thing folds into the included carry bag, so a 5.85 pound kit can move from a suburban garden to a darker field without a car boot full of gear.
What you will actually see with the 70mm
Expect a bright, detailed Moon at low power, the four Galilean moons of Jupiter changing position between views, and Saturn with its rings as a small but unmistakable oval. The Andromeda Galaxy and the Orion Nebula are reachable as fuzzy patches, not resolved objects. That limit comes from aperture, not quality.
Where the 70mm runs out of road
At 70mm you are collecting roughly a fifth of the light of a 150mm reflector, so faint galaxies and globular clusters stay unresolved. The 400mm focal length also means a modest maximum magnification, so there is little planetary detail beyond Jupiter’s belts and bands. If deep sky is your interest, step up to pick 2 or pick 3.
2. MEEZAA 150EQ Newtonian Reflector – Best Light-Gathering for the Money
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
150mm aperture
650mm focal length
German equatorial mount
Slow-motion controls
Pros
- Largest aperture in this roundup
- Equatorial mount tracks smoothly once aligned
- Generous accessory package with moon filter and carry bag
- No tools needed for assembly
Cons
- Newtonian mirror needs periodic collimation
- Heavy and awkward for one person to move
- Included Kellner eyepieces are entry level
Here is the honest core of this whole guide. A 150mm mirror collects roughly four and a half times the light of the 70mm refractor above, and this is the only scope in our list that puts that much aperture on a German equatorial mount inside the budget.
That combination changes what the sky looks like. At 150mm the Cassini Division in Saturn’s rings separates, you get colour banding on Jupiter, the Orion Nebula shows structure rather than a grey oval, and globular clusters such as M13 begin to break into individual stars at the edges.
The equatorial mount is the reason this scope beats its rivals. Once polar-aligned, the slow-motion knobs let you follow an object drifting across the field without touching the tube, which is exactly what happens over ten minutes of planetary observation. Reviewers repeatedly note that assembly weight and the eyepiece upgrade are the two real caveats.
The accessory package is unusually complete: 25mm and 10mm eyepieces, a 2x Barlow lens taking you from 26x to 130x, a red dot finder, a moon filter, a phone adapter and a large carry bag. For a first Newtonian, buying the eyepieces separately would be a false economy, because most of the budget would go on the mount and tripod instead.
When a 150mm Newtonian earns its place
Choose this if you have a reasonably open horizon and want the most sky per unit of money. The same dark-sky object that is invisible in a 70mm refractor shows real structure here, and the equatorial mount keeps it in view while you look. It suits an adult or a teenager who will actually sit with a target for ten minutes.
Where it will frustrate you
Two things. A Newtonian reflector needs its mirrors collimated, and alignment can drift after the tube is transported, so budget fifteen minutes for the first session and check it again after moving the scope. Second, this is a big, heavy instrument on a tripod, and one person carrying it alone in the dark is a genuine annoyance. The all-plastic focuser and fiddly phone holder are minor by comparison.
3. Sky-Watcher Heritage 150 Tabletop Dobsonian – Simplicity With the Same Aperture
Sky-Watcher Heritage 150 Tabletop Dobsonian Telescope – Perfect for Beginners, Easy Setup, Portable, and Fun (S11710)
150mm aperture
750mm f/5
Collapsible tube design
Tabletop Dobsonian base
Pros
- Same 150mm aperture as the equatorial Newtonian
- No polar alignment learning curve
- Collapsible tube stores easily
- Rubber feet damp vibration
Cons
- Needs a table or stand at a comfortable height
- No tracking so targets drift at high power
- Basic helical focuser and single eyepiece set
The Dobsonian answer to the same 150mm aperture, and the reason so much advice about this budget points at a 6-to-8 inch Dob. It is the same light-gathering power as pick 2, delivered on a base with no polar alignment, no counterweights and no slow-motion cables.
You put it on a table, you push the tube toward the object, you look. That is the entire procedure. A toroidal altazimuth base with a friction brake lets you move the tube with one finger and still hold it steady at 100x, which is a genuine luxury compared with fighting a stiff tripod knob.
Optically it is a fast f/5 design with a 750mm focal length and a borosilicate parabolic primary mirror carrying Radiant Aluminum Quartz coating. Reviewers describe the result as crisp and contrast-rich, particularly on lunar detail and on the brighter planets, which is exactly what a short focal length plus a large aperture delivers.
The collapsible tube is the detail we appreciate most. It folds down for storage in a small flat space while keeping collimation, so the scope does not need re-aligning every time you carry it out of the cupboard. It also means this is a realistic gift for someone in a flat without a garden.
Who the tabletop Dobsonian suits
If you have never owned a telescope and you do not want to spend a weekend learning polar alignment, this is the least intimidating way to reach a 150mm mirror. It is also the one our team would pick for children or for a house full of people who will all want a look through the eyepiece at once.
Where it falls short
You need something to stand it on at a height that suits you, and a table indoors limits you to observing through a window or carrying the whole thing outside each time. There is no tracking, so anything above about 50x drifts out of the field within a couple of minutes, and the 1.25 inch helical focuser is a step down from a rack-and-pinion unit.
4. Celestron StarSense Explorer DX 130AZ – Best Telescope for Finding Objects
Celestron StarSense Explorer DX 130AZ Smartphone Guided Newtonian Telescope
130mm aperture
650mm focal length
StarSense app sky plate-solving
Dual-axis slow-motion
Pros
- StarSense app points accurately at real targets
- 130mm mirror shows Moon
- Saturn and the Orion Nebula clearly
- Dual-axis slow-motion controls ease tracking
- Sets up in roughly 30 minutes
Cons
- Tripod knobs and mount described as flimsy and vibration sensitive
- Phone holder neck shakes in light wind
- Tube clearance limits viewing near the horizon
The single hardest part of new telescope ownership is not the optics. It is finding the Andromeda Galaxy in a dark sky when you are standing in a field holding a torch. StarSense solves that, and it is why this Celestron appears in almost every beginner recommendation we researched.
You hold your phone up to the telescope, the app matches the star pattern it sees against a database, and the red dot finder lights up with arrows telling you which way to turn. Experienced observers quoted in the reviews say the pointing is more accurate than many computerized GoTo mounts at several times the cost, which is a strong claim for a phone camera doing the work.
Optically it is a 130mm Newtonian with high-reflectivity aluminium and silicon dioxide mirror coatings, a 650mm focal length and a Dawes limit of 0.89 arc seconds. In practice that means the Moon’s terminator, Saturn’s ring tilt and the four Galilean moons all render well, and the Orion Nebula and Andromeda are visible as extended smudges rather than points.
The app also curates a list of tonight’s best targets based on your time and location, which quietly solves another beginner problem: what to look at when you have no idea what is up.
When StarSense earns its money
Pick it if you are buying for someone who has never looked through a telescope, or if your observing time is a spare ten minutes rather than a whole evening. Removing the hunt for objects means every one of those minutes is spent looking rather than searching, and at 18 pounds it is still light enough to move solo to darker ground.
The vibration problem nobody mentions in the ads
The most consistent complaint across more than a thousand reviews is the tripod. The mount and its knobs are described as flimsy and very sensitive to vibration, and the phone holder neck flexes in a light breeze, which is unhelpful when the app is doing the pointing. Add the tube clearance, which restricts how high you can follow an object near the horizon. It is a fine scope; it just needs a steadier tripod than the one in the box.
5. Gskyer 130EQ Reflector – Best for Tracking on a Tripod
Gskyer 130EQ Professional Astronomical Reflector Telescope
130mm aperture
650mm f/5
German equatorial mount
Three eyepieces plus 3x Barlow
Pros
- Equatorial mount tracks objects across the sky
- Short f/5 tube is more compact than typical 130mm Newtonians
- Three eyepieces and a 3x Barlow give wide magnification range
- Highest rated Newtonian in this roundup
Cons
- 30.1 pounds makes it heavy and awkward
- Newtonian collimation is required
- Bluetooth remote still needs practice to align
This is the compromise pick between pick 2’s raw aperture and pick 4’s convenience. You get a German equatorial mount that tracks in right ascension and declination, at 130mm rather than 150mm, on a short f/5 tube that is far more manageable than a full-length 130mm Newtonian.
That f/5, 650mm focal length is a wide-field design. It suits large deep-sky objects, open clusters and the Andromeda Galaxy, where a longer focal length would spread the same light over more sky and dim the view. For planets, the f/8 scopes further down this list are the better tool.
Three eyepieces plus a 3x Barlow lens give you a usable range without any further spending, and the toothless focusing base keeps the focuser smooth. Reviewers rate this at 4.4 stars and single out the EQ mount’s tracking as the reason it outperforms cheaper 130mm Newtonians on the same tripod footprint.
The Bluetooth wireless remote pairs with iPhone or Android without an app download, so first-night photos are a two-tap job. Owners like the convenience, with the fair warning that lining a phone up behind the eyepiece still takes a few attempts.
Why the equatorial mount matters for photography
A German equatorial mount is the first step toward actually photographing the sky. Once aligned, the right ascension axis can hold a target steady, which is the thing a plain altazimuth tripod simply cannot do. A camera or phone at the eyepiece on this mount can hold a target long enough for short exposures of bright targets.
What 30 pounds feels like
This is the heaviest non-smart scope in the roundup at 30.1 pounds, and owners name weight as the top reservation. Carrying it from a car boot to a pitch at night in the dark is a two-person job, and the tube plus counterweight assembly is easy to lose grip on. Budget for a folding wagon or a second person.
6. DWARFLAB Dwarf Mini Smart Telescope – Best for Astrophotography
DWARFLAB Dwarf Mini Smart Telescope – 1.85lb Portable Astronomy Telescope
30mm objective with Sony IMX662 sensor
1.85 pound body
150mm focal length
Auto GOTO
Pros
- Pocket-sized and quick to image on
- Plate solving finds and tracks deep-sky targets
- Built-in light pollution filters aid urban imaging
- Internal stacking and cloud processing save finished images
Cons
- Low sensor resolution rules out large prints
- Weak planetary detail from the short focal length
- WiFi connection can be finicky on first use
No competitor roundup we studied covers smart telescopes, yet they come up constantly in community discussions at this budget, and the pattern of advice is consistent: very portable, very easy, and not much use on planets. That description fits this 1.85 pound unit exactly.
There is no eyepiece to squint into. The Stellar Studio app gives you an interactive sky atlas, and the auto GOTO with plate solving finds and tracks a target on its own. Reviewers report roughly three minutes from unpacking the case to a first stacked deep-sky image, which is faster than any conventional setup in this guide.
The imaging hardware is where the money went. The Sony IMX662 sensor records 90-second exposures in equatorial mode, the scope captures dark frames automatically, and sub-frames are stacked internally before cloud processing finishes the job. Built-in light pollution filters make it usable from a city balcony, which is the situation most of us actually observe from.
It also handles solar imaging with the included filter, which no other scope here mentions. Our advice is to leave the sun alone until you have read the safety guidance, then use the supplied filter and never a telescope unfiltered.
What smart imaging is genuinely good at
Open clusters, bright nebulae like the Orion Nebula, and wide galaxy fields are the strengths, because stacking short exposures pulls faint signal out of a small sensor. This is the only pick in the roundup that produces a finished astronomical photograph on its own, and for astrophotography-curious beginners it is the shortest path in.
Where it stops
A 30mm objective with a 150mm focal length has almost no planetary capability, and the community consensus is blunt that smart scopes of this size are not the tool for Saturn. The sensor resolution also means files are sized for a phone screen, not a wall. For equatorial mode over longer sessions, a fluid-head tripod and a power bank are separate purchases.
7. Celestron PowerSeeker 127EQ Reflector – Best Entry Reflector With Tracking
Celestron PowerSeeker 127EQ Reflector Telescope for Home Astronomy
127mm aperture
1000mm focal length
Manual German equatorial mount
20mm and 4mm eyepieces
Pros
- Slow-motion controls allow smooth manual tracking
- 1000mm focal length supports high magnification on planets
- Compact and light enough to move alone
- Two year warranty
Cons
- Newtonian collimation has a learning curve
- Mount and tripod described as flimsy with backlash
- Included 4mm eyepiece and finder are weak
The Celestron name carries a lot of weight for a reason, and this reflector is the most established conventional telescope in the group with close to 9250 ratings behind it. At 127mm aperture and 1000mm focal length it sits in the middle of the field: more light than any refractor here, more magnification reach than any Dobsonian here.
That 1000mm focal length is the planetary configuration. The Moon fills a 1.25 inch eyepiece, Jupiter shows its belts, and the longer tube narrows the field of view to 2.5 degrees, which keeps a planet steady against the background instead of letting it drift through.
Reviews split predictably. Enthusiasts call it excellent value once it is collimated and balanced, and they praise the slow-motion altitude rod for nudging an object back to centre. Buyers who never got past assembly describe the fiddly collimation process, the weak finder and a wobbly equatorial mount as the reason they are unhappy.
It weighs 13 pounds, which is genuinely light for an equatorial mount, and that matters if your dark-sky site is a twenty-minute walk rather than a drive.
When a long focal length is the right call
Planets and the Moon. Every doubling of focal length doubles magnification, so 1000mm gives you real reach without a Barlow lens, and it does so on a tube that is still portable. It is also the pick for anyone who wants to try planetary sketching with a sketch pad, where a stable, narrow field helps enormously.
The parts you will want to replace
The 4mm eyepiece is faint and low quality, and the included finder is described as weak, so budget for a 25mm wide-field eyepiece and a better finder early. The tube cap is also widely reported to crack, so store the tube in a sheltered spot rather than leaning it against a wall.
8. Hawkko 90mm AZ Refractor – Best Long Focal Length on a Stable Tripod
Hawkko 90mm Aperture 900mm Telescope for Adults High Powered – Professional Multi-Coated Refractor Telescope for Astronomy Beginners (36X-270X) with AZ Mount, Phone Adapter and Carry Bag
90mm aperture
900mm f/10 focal length
Full multi-layer coating
Stainless steel tripod
Pros
- Largest aperture and longest focal length in the refractor group
- Multi-coated 90mm lens gives bright images
- Stainless steel tripod and smooth rotation feel stable
- Complete kit with zenith mirror and accessory tray
Cons
- 900mm tube is bulky to carry
- Long focal ratio demands careful focusing at high power
- Generic accessories limit performance at maximum power
If your list is dominated by planets and the Moon, aperture alone is the wrong filter. A 90mm refractor with a 900mm focal length is a long, narrow instrument built for magnification, and it is the longest-focal-length refractor optical design in this roundup.
At f/10 the exit pupil is narrow, so the image is bright and contrasty even on a faint target, and the 900mm focal length gives 36x to 270x magnification depending on the eyepiece. The Dawes limit of 1.29 arc seconds is a useful number here: it tells you what detail the optics can actually resolve rather than what the packaging claims.
The stainless steel tripod is a real difference from the flimsy aluminium legs on the cheaper scopes here. With 360 degree rotation and a 28 to 46 inch height range, it resists the vibration that makes high-power planetary observing frustrating, and the mount is easy to point at a moving target.
Owners credit the multi-layer coating, which the manufacturer puts at roughly 73% light transmittance, and the completeness of the kit: finder scope, zenith mirror, 25mm and 10mm eyepieces, a 3x Barlow, accessory tray, phone adapter and carry bag. Assembly is reported at about fifteen minutes.
When a refractor earns its place
A refractor needs no collimation, holds collimation, and shows contrast on planetary detail better than a reflector of the same aperture. If your targets are Saturn, Jupiter and the Moon, and you want a sealed tube that just works every time you take it out, this design suits the job better than a larger Newtonian.
Chromatic aberration is the trade-off
A single achromatic doublet does not bend all wavelengths of light to the same point, so bright objects show purple fringing, most visibly on Jupiter and on the lunar limb. There is no fix without spending on extra-low-dispersion glass, so accept the fringe, or treat the 150mm scopes as the alternative.
9. Celticbird 80mm AZ Refractor – Best for Kids and Small Spaces
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
20mm and 9mm eyepieces
Moon filter
Pros
- Moon filter improves contrast on bright targets
- Everything packs into the included backpack
- No-tool assembly suits ages 8 to 12
- Tripod adjusts low enough for younger children
Cons
- Short focal length caps useful magnification
- Small aperture limits faint deep-sky objects
- Lightweight mount and tripod shake at higher power
This is the pick we would put in front of a child aged eight to twelve, and the reason has little to do with optics. It weighs 5.8 pounds, it assembles without tools, and it folds into a backpack, so a young observer can carry it to a field or a campsite on their own.
The moon filter is the standout feature. It passes 13% of the incoming light, which darkens the bright lunar surface and pulls out subtle crater detail and the shadows inside larger craters, so a beginner sees something interesting on the very first night rather than a flat white disc.
Optically it is a straightforward 80mm fully coated refractor with a 600mm focal length at f/6.7, a 5×24 finder scope, and 20mm and 9mm eyepieces giving 30x and 66x. At 80mm the Moon, Venus and Jupiter are the reliable targets, along with the brighter deep-sky objects such as the Pleiades and the Orion Nebula.
The tripod adjusts from 17.7 to 52 inches, which lets a child see into the eyepiece without standing on a box. That small ergonomic detail does more for a young observer’s experience than a slightly larger aperture would.
Best first telescope for a family
Two people can look at the Moon at the same time if you take turns, the setup takes minutes, and nothing here needs collimation or polar alignment. It is a good shared birthday present for a family that has never owned a telescope, and the included phone adapter lets a child photograph the Moon and compare frames on successive nights.
Where a child will outgrow it
At 80mm aperture the deep sky is limited, and the 66x top magnification is modest. The lightweight mount and tripod also shake noticeably at the higher end, which is frustrating when a keen nine-year-old has just found Saturn. When they are ready for more, a 130mm or 150mm reflector is the natural next step.
10. Koolpte 80mm AZ Refractor – the Brightest Grab-and-Go Scope Per Pound
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 aperture
600mm f/6.7 focal length
Fully multi-coated optics
25mm and 10mm eyepieces
Pros
- 4.3 stars across close to 4000 ratings
- Multi-coated lens gives bright clear views
- No-tool setup gets beginners observing quickly
- Compact tube packs into the carry bag
Cons
- Modest 80mm aperture limits faint deep-sky objects
- Entry-level eyepieces reduce quality at high power
- Small altazimuth mount and light tripod shake at high power
Koolpte is the smaller-sibling alternative to the Celticbird above, and at 4.3 stars across close to 4000 ratings it is the second most proven design in this roundup. Where the difference sits is in the coatings and the eyepiece set, and in a slightly lower carrying weight.
The 80mm objective is fully multi-coated for high transmission, which is a step up from a single coating and shows as a brighter, cleaner lunar image. The 25mm and 10mm eyepieces give 24x and 60x, and the 3x Barlow takes you to 180x on the Moon, which is more than the aperture can really support but is a fun thing to try with a child.
The no-tool assembly is genuinely quick, and the 600mm tube is short enough to pack in the included carry bag. Owners single out brightness, quick assembly and the bundled phone accessories as the three reasons the scope earns its place in a household full of casual observers.
A 5×24 reflex finder scope comes in the box, so locating targets does not depend on a phone app. Some observers prefer that: fewer things to charge, fewer things to break, and a finder that works in the rain.
Best for a small apartment or a balcony
Short tube, carry bag, no tools and a light mount add up to the easiest scope here to move from a hallway cupboard to a balcony. It is a sensible choice for someone in a city who wants to look at the Moon and planets but will never drive to a dark site.
Light pollution is the limiting factor, not the scope
At 80mm from a bright city, the sky background swallows anything faint. You will see the Moon, the planets and the brightest clusters, and little else. If you can get an hour of travel to darker ground, a larger aperture in this budget buys far more than a better-coated small one.
How to Choose a Telescope Under 500 Dollars
Aperture is the spec that decides everything
Aperture is the diameter of the lens or primary mirror, and light-gathering ability scales with the square of that number. That is why a 150mm mirror shows structure in the Orion Nebula where a 70mm refractor shows a smudge, and why every honest guide at this budget leads with aperture rather than magnification.
The practical rule is roughly 2x magnification per inch of aperture before you are asking for more than the atmosphere can deliver, and about 5x as an absolute ceiling. So a 150mm Newtonian tops out around 190x of genuinely useful power, and the 600x figure printed on cheap boxes is a claim about an accessory eyepiece, not about the telescope.
Refractor vs reflector vs catadioptric
Refractors use a lens, need no maintenance, and show contrast well, but aperture scales with price quickly, which is why the budget ones stop at 70mm to 90mm. Reflectors use a mirror, deliver far more aperture per unit of money, and need occasional collimation. Catadioptric designs fold a long focal length into a short tube, and none reach this budget in a form we would recommend.
Match the type to the target. Planets and the Moon favour a long focal length refractor, deep sky favours a fast Newtonian, and setup simplicity favours a Dobsonian. Our beginner refractor guide goes deeper on the lens options.
Chromatic aberration and the purple fringe problem
Chromatic aberration is the reason cheap achromatic refractors show a purple halo around bright objects, and it is one of the community’s most common complaints in this price range. It appears worst on Jupiter, on the lunar limb, and at high magnification, and it cannot be fixed without extra-low-dispersion glass that costs far more than this budget allows.
Two answers work. Buy a reflector instead and accept periodic collimation, or keep the refractor and treat the fringe as the price of never aligning a mirror again. If children are part of the plan, our guide to telescopes for kids compares the light, sturdy beginner options.
Mount stability and how to stop wobble
Wobble is the most common reason a cheap telescope ends up in a cupboard. Every review of the tripod-mounted scopes here mentions vibration, and the fix is a short numbered list: shorten the tube overhang so the optical tube assembly sits over the tripod legs rather than beside them; tighten every tripod knob fully and check them before each session; avoid extending the legs to maximum height in wind, since a lower centre of gravity is steadier; and counterbalance an equatorial mount before adding a camera or eyepiece load.
If wobble persists after all four, replace the tripod before replacing the telescope. A steadier mount improves a modest scope far more than a bigger aperture on the same wobbly legs.
Focal length, focal ratio and honest magnification
Focal ratio is focal length divided by aperture, and it tells you what an image looks like rather than how much you can see. A fast f/5 Newtonian gives a wide, bright field suited to deep sky, while a slow f/10 refractor gives a narrow, high-contrast field suited to planets. Slower focal ratios are easier on aberrations, which is one reason budget reflectors are often f/5 to f/8.
What a 500-dollar telescope actually shows
Set expectations here. A 130mm to 150mm reflector comfortably shows lunar craters and rilles, Saturn’s rings with the Cassini Division at good seeing, Jupiter’s belts, bands and four Galilean moons, the Orion Nebula’s wings, the Andromeda Galaxy, several globular clusters and dozens of Messier objects. It will not show faint galaxies from a city backyard, and it will not resolve anything on the faint outer edge of the Whirlpool Galaxy.
One more piece of community advice worth taking seriously: plenty of experienced amateurs start with a cheap pair of binoculars such as a 7×50, learn to find the Moon and the Orion Nebula unaided, and only then buy a telescope. It costs a fraction of the budget and removes the single biggest reason beginners give up.
Observing from a light-polluted city
City observing rewards a different target list. Skip the galaxies and faint nebulae entirely and spend your time on the Moon, the planets, double stars, the Pleiades and one or two bright clusters. High magnification is your friend in a bright sky, because it raises the object’s brightness above the background.
A light pollution filter helps more on imaging than on visual observing, and it costs money you are probably better spent on aperture. If you can reach darker sky once a month, do that, and treat the city sessions as lunar and planetary nights. We cover the options in our smart telescope picks, where built-in filtering is standard.
Frequently Asked Questions
What is the cheapest but best telescope?
The cheapest genuinely usable telescope is a 70mm to 80mm altazimuth refractor with a tripod and a finder scope. It will show you the Moon, the phases of Venus, Jupiter’s four Galilean moons and Saturn as a small ringed oval, and that is enough to decide whether you enjoy astronomy. Expect a 1.25 inch focuser, one or two basic eyepieces and a mount that will wobble above about 60x.
What is the best telescope to buy for the money?
At this budget the best value is the largest aperture you can carry, not the highest magnification number. A 6-inch Dobsonian or a 6-inch Newtonian reflector on a German equatorial mount gathers roughly four times the light of a 70mm refractor, so galaxies and nebulae go from invisible smudges to recognisable objects. If a smartphone app that points the telescope for you matters more than aperture, a StarSense-guided 130mm Newtonian is the alternative.
Is a 6 inch telescope better than an 8 inch telescope?
An 8 inch aperture gathers about 78% more light than a 6 inch and resolves noticeably finer planetary detail, so it is the better instrument if your budget reaches one. The catch is weight and stability: a larger Dobsonian or equatorial Newtonian is harder to carry, harder to stabilise and easier to shake on a mediocre tripod. If the 8 inch option relies on a flimsy mount, a solid 6 inch on a steady base will deliver better views in practice.
Which telescopes suffer from chromatic aberration?
Cheap achromatic refracting telescopes suffer most, especially achromatic doublets of 70mm to 90mm aperture at long focal lengths. You see a purple or blue halo around bright objects, most clearly on Jupiter and on the edge of the Moon. Reflectors do not have this problem because they use mirrors instead of glass, and catadioptric telescopes avoid it by using a corrector plate rather than a full objective lens.
How do I stop my telescope from wobbling?
Most wobble comes from the tripod, not the optics. First, keep the optical tube assembly centred over the tripod legs instead of hanging out to one side. Second, tighten every knob fully, including the spreader lock, and check them at the start of each session. Third, avoid maximum leg extension outdoors, because a lower setup resists wind and vibration far better. Finally, on an equatorial mount balance the tube before you add a camera, and if wobble persists, replace the tripod before you replace the telescope.
Why is everything upside down when I look through my telescope?
A standard Newtonian reflector and most other telescopes produce an inverted image, so the sky appears rotated 180 degrees and words read backwards. This is normal optical behaviour and has no effect on what you are observing, because there is no fixed up on the sky. A star field looks identical inverted. An erecting prism or an erect-image diagonal corrects it for terrestrial viewing and for beginner use, at a small cost in light and image quality.
Our Final Verdict on the Best Telescopes Under 500 Dollars
For most readers, the Gskyer 70mm refractor is the right first telescope under 500 dollars, because more than 22000 people have already confirmed that it assembles easily, packs into a bag and shows a genuinely good Moon. Buy it for a child, a gift or a first hour under the stars.
Buy a bigger aperture if you want to see more. The MEEZAA 150EQ Newtonian gives the most light in this roundup and tracks properly once aligned, while the Sky-Watcher Heritage 150 tabletop Dobsonian gives the same 150mm mirror with no polar alignment at all. The Celestron StarSense Explorer DX 130AZ is the pick for anyone whose main obstacle is finding objects, and the DWARFLAB Dwarf Mini is the only one here that produces finished astrophotographs on its own.
Whichever you choose, remember that the eyepieces in the box are the weakest link. A good 25mm wide-field eyepiece and a 10mm Plossl transform more of these scopes than a modest aperture upgrade would. Our guides to the best Dobsonians for deep sky and the best telescopes for astrophotography cover the next steps once this one is mastered. Updated for October 2026.
