Amateur astronomy comparison — 2026 edition
Find the telescope
that really matches the sky you can actually see
Refractors, reflectors, Dobsonians and folded tubes; equatorial, alt-azimuth and GoTo mounts; star trackers, binoculars and planetary cameras — and the eyepieces, Barlows, diagonals, filters and adapters bought the week after. Compared on the lines that decide what a night actually shows: what the aperture collects, what the focal ratio frames, what a mount is rated to carry before a camera goes on it, and which band a filter really passes. Priced on the Amazon store in your own country.

Every family, from the mirror to the coin cell
Astronomy instruments first, the brand after
23 families that gather light, carry it or record it, 6 that shape, filter and protect it. Each hub compares one family and opens with a direct answer to “which one should I buy?”, followed by the published specification most often misread when buying it.
- Refractor telescopes A sealed tube, a lens at the front, and color to account for
- Reflector telescopes The most aperture per euro, and an alignment to keep
- Dobsonian telescopes A big mirror on a box that costs almost nothing
- Catadioptric telescopes A long focal length folded into a short tube
- Smart telescopes No eyepiece at all — a sensor, a phone and a stack
- Travel telescopes The one that fits in the bag is the one that gets used
- Telescopes for children A steady mount beats a big number on the box
- Astronomy binoculars Two eyes, a wide field, and no setup at all
- Monoculars Half the weight, half the glass, one eye
- Spotting scopes Daylight optics that double for the Moon
- Equatorial mounts One axis against the turning sky — once it is aligned
- Alt-azimuth mounts Up-down, left-right, and nothing to align
- GoTo mounts A database, two motors, and an alignment that has to be honest
- Star trackers A camera, a lens and one motor against the rotation
- Planetary cameras Thousands of frames, and only the sharpest kept
- Guide scopes A small tube whose only job is to watch one star
- Finder scopes The part that decides whether pointing is a pleasure
- Star projectors A ceiling instead of a sky, and two very different kinds
- Telescope eyepieces Magnification is a division, not a number on a box
- Zoom eyepieces One barrel across a range, with a field that narrows
- Eyepiece sets A spread of magnifications, or four that overlap
- Barlow lenses It multiplies the focal length, and the eye relief survives
- Nebula filters They pass the lines the gas emits and block the rest
- Solar filters Full aperture, in front of the telescope, and nowhere else
- Moon filters A full Moon in a large telescope is genuinely too bright
- Color planetary filters Each color suppresses a contrast so another one shows
- Phone adapters Alignment in three axes, held by one clamp
- Red dot finders No magnification, both eyes open, and pointing becomes obvious
- Counterweights Balance is what lets a small motor move a heavy tube
How SkyVerdict works
What every page here undertakes
-
Ordered by what makers write down, not by what they pay out
Commission has no say in where an instrument ranks. When a modest telescope on a steady mount is the sensible first purchase and the larger one beside it is not, the page says so plainly — and when a dearer eyepiece earns its cost because the maker publishes an eye relief that lets you keep your spectacles on, the page explains exactly that.
-
The number that settles it, in the unit its maker used
Aperture kept apart from magnification, which is a division and not a property of a telescope; a focal ratio written as the quotient it is; a mount’s payload quoted as the maker quotes it, for observing, without being silently promoted into a photographic rating; a filter named by its bandpass rather than by a three-letter label. Each appears in the maker’s unit with its source named. A figure no maker published is marked as missing, never filled in.
-
Pointed at whichever Amazon store serves where you are
We do not switch stores on you. The button opens the Amazon this site is built for; the figure beside it is read for the country you browse from. A astronomy instruments model we have not verified on that store gets a search link, never a dead end.
Who each scope is for
Three scopes, three different skies
Drawn from three different aisles, in the wording of each scope page.
A spectacle wearer who wants one eyepiece instead of four, with eye relief guaranteed at every setting
High-power lunar and planetary work on a long-focal-length telescope, by somebody who does not wear spectacles at the eyepiece
An observer in a suburban sky who wants the effect explained before buying, and will take the glass on trust
The figures that decide what you see
What the figures on a scope really mean
Ranges observed across the published products. A figure is only shown when at least five models state it.
| Measurement | Range | Median | Models |
|---|---|---|---|
| Aperture | 4 – 203 mm | 70 mm | 93 |
| Barrel size | 1.3 – 965 in | 1.3 in | 33 |
| Exit pupil | 1.2 – 5 mm | 4.1 mm | 27 |
| Magnification | 5 – 25 x | 10 x | 26 |
