Which telescope should you buy?
For most first-time buyers the answer is a 130 to 150mm tabletop reflector under $500, or an 8-inch Dobsonian once budget and storage allow. Both give you real aperture, the width of the mirror or lens that decides what you can actually see, without an equatorial mount to learn or tracking motors to pay for.
That is the answer for most people. It may not be the answer for you. A telescope that has to fit in a closet and travel by bus is a different shopping problem than one that lives in a garage. A telescope bought for a seven-year-old has different requirements than one bought for an adult who has used binoculars for years. The finder above asks eight questions, scores the same 27 telescopes against your answers instead of the average buyer’s, and gives the reasons behind every recommendation. It takes about two minutes. The longer guide to choosing a telescope covers the same ground in prose.
How the finder decides
Your budget is a hard limit rather than a preference. Only telescopes that sell in the band you pick are considered, and everything else is dropped before any scoring happens.
Three rules then protect against a bad match at any price. For a child under 10, anything heavy, anything on an equatorial mount and anything hard to collimate is removed, because those are the telescopes that end up in a closet after one frustrating night. Anything too heavy to carry in a bag is removed if it has to travel that way. Finding preference is exclusive at the extremes: manual removes every smart telescope, and smart removes every telescope with an eyepiece, because the two answer different questions.
Everything still standing is scored on fit. Each question you answer casts a weighted vote, and the weights are in the table below. A skipped question is not guessed at; it contributes nothing. The match percentage is calculated only from the questions you answered, so four answers and eight answers are each judged on their own terms. It is capped at 98%, because no telescope is a perfect answer to every question.
| Question | Weight | What it changes |
|---|---|---|
| Who is it mainly for? | 1.5 | Weights kid-friendliness and ease of use. For a child under 10 it also removes heavy telescopes, equatorial mounts and hard-to-collimate optics outright. |
| What do you most want to see? | 2 | The heaviest single weight in the finder: it scores each telescope's planet and deep-sky ratings against what you want to look at. |
| Where will you observe from? | 1 | Scores how well each telescope copes with a bright sky, and gives smart telescopes credit where light pollution is heavy. |
| How will it live and travel? | 1.8 | Scores weight class against how far the telescope has to travel. Anything over 25 kg is removed if it has to fit in a bag. |
| How do you want to find things? | 1.6 | Matches the telescope's finding system to your preference. Choosing manual removes smart telescopes; choosing smart removes everything else. |
| Do you want to take photos? | 1.4 | Scores each telescope's photography level: none, phone snapshots, planets, live stacking or deep-sky imaging. |
| What can you spend? | hard filter | Sets the price band the finder searches. Only telescopes in your band, or that regularly sell into it, are considered. |
| How much fiddling are you happy with? | 1.2 | Scores setup time and maintenance against your patience, and steers away from equatorial mounts if you want zero fuss. |
| Have a design preference? | 0.8, only if answered | Only counts if you answer it. Adds a light preference for the optical design you picked. |
| If | Then |
|---|---|
| The child is under 10 | No heavy telescopes, no equatorial mounts, no Bird-Jones optics |
| It is mainly for a teenager | Nothing over 25 kg |
| It has to fit in a bag | Nothing over 25 kg |
| You picked "I’ll learn the sky" | No smart telescopes |
| You picked "The app does everything" | Only smart telescopes |
| You picked "Just looking", no photos | No smart telescopes |
Each rule above is dropped again if applying it would leave nothing to recommend.
What each answer changes
Budget and aperture
Money buys aperture before it buys anything else. Under $200 buys 70 to 130mm, enough for craters on the Moon, Saturn’s rings and the four bright moons of Jupiter. $200 to $500 moves into 130 to 200mm, where Jupiter’s cloud belts appear and galaxies start showing structure. Past $1,000 the extra money buys motors, tracking and cameras, not a bigger mirror.
Planets or deep sky
Planets are small and bright, so they reward sharp optics and a long focal length; even a 70mm refractor shows Saturn’s rings. Galaxies, nebulae and star clusters are big and faint, so they reward light grasp: an 8-inch mirror collects roughly eight times the light of a 70mm lens, since light grasp scales with the square of the aperture. A 130 to 150mm reflector is the middle ground, good at both instead of excelling at either.
Your sky
Light pollution hides faint objects no matter how large the mirror is. From a city center the Moon, planets, double stars and brightest clusters hold up well, and smart telescopes do particularly well because they stack exposures and subtract the background glow. Suburbs add the Orion Nebula, the Andromeda Galaxy as a soft smudge and the larger globular clusters. Under a dark rural sky a 150mm telescope can outperform a much larger one used from a city.
Who it is for, and where it lives
A telescope that does not fit its owner gets used twice and then stored. A child under 10 needs the eyepiece at their height and a tube that survives being knocked, which is why tabletop reflectors dominate that answer. Weight decides the rest: under 3kg fits a backpack, 3 to 14kg is one trip to the yard, and an 8-inch Dobsonian is a two-trip telescope that wants a permanent corner of a room.
Finding, photos and upkeep
Manual finding means a star chart and nudging the tube by hand, and it puts every dollar into the optics. Phone-guided finding uses your phone’s camera to work out where the tube points and shows arrows to the target, with no motors or batteries. GoTo slews and tracks after a short alignment, which costs money and needs power but turns ten minutes of searching into ten seconds. A smart telescope replaces the eyepiece with an app. Photography splits the same way: phone snapshots of the Moon work through almost any telescope, while galaxies and nebulae need a mount that tracks the sky during long exposures. Upkeep is the last trade. Refractors need nothing, reflectors need occasional collimation and equatorial mounts need polar alignment every session.
The 27 telescopes it chooses from
Every telescope in the finder is a current model that is buyable on Amazon today, checked against live listings on 2026-09-17, and the range runs from tabletop reflectors under $100 to GoTo and smart telescopes over $1,000. There are no Orion telescopes in it because Orion Telescopes & Binoculars closed in 2024 and its products are no longer reliably in stock. Bird-Jones reflectors, a compact design that uses a lens to shorten a mirror’s focal length, are included but rated honestly: they are hard to collimate and rarely reach true sharpness, and their quality score says so. The Celestron AstroMaster 114EQ is left out because in every combination of answers where it could have appeared, another telescope in the same band scored better.

When it is worth stretching to the next price band
Sometimes the finder shows a fourth pick from the band above yours, marked as a stretch. It appears only when moving up improves your fit by a meaningful margin, and only once you have answered enough questions for the comparison to mean something. In practice that is two situations: going from a 70mm telescope to a 130mm one, which is a real jump in light grasp rather than a marginal upgrade, and going from a manual telescope to a tracking mount when you said you want real astrophotography. If no stretch pick appears, your own band already has a good answer.
What the finder cannot know
No quiz can measure your sky on a given night, how patient you will be with a stubborn finderscope or whether it gets carried outside once the first week’s novelty wears off. Those things decide how much you enjoy a telescope as much as any spec does, which is why two people can own the same model and disagree about it completely. The finder scores what can be scored: aperture, weight, optics, mount and features against the answers you give it. Before you commit, look through the Telescope View Simulator at the Moon, Saturn or a galaxy at the aperture and focal length of each recommendation.

Questions people ask
Which telescope should I buy as a beginner?
A 130 to 150mm tabletop reflector under $500, or an 8-inch Dobsonian if budget and storage allow. Which of the two suits you depends on your budget, who will use it, what you want to see and how far it has to travel. The finder above scores 27 current telescopes against your own answers in about two minutes.
Is a telescope quiz reliable?
This one scores real trade-offs against a curated catalog of 27 current telescopes rather than ranking by popularity. Your budget acts as a hard filter. Three rules then remove bad matches for children, for telescopes too heavy to carry and for mismatched finding systems. Everything left is scored on aperture, weight, optics, mount and features against the questions you actually answered.
What telescope should I get to see planets?
Planets reward sharp optics and a long focal length more than raw aperture, which is why even a 70mm refractor shows Saturn's rings clearly. Larger apertures still help, since more light means a brighter, more detailed image at high magnification. Tell the finder that planets are your priority and it weights planetary performance heavily, favoring long focal lengths like Maksutovs and Schmidt-Cassegrains.
Are smart telescopes worth it?
Smart telescopes replace the eyepiece with an app that finds, tracks and stacks images on your phone screen. They excel from light-polluted cities and need almost no setup, but they disappoint anyone who wanted to look through a telescope by eye. The finder asks how you want to find things and scores them accordingly rather than assuming everyone wants one.
Refractor or reflector for a child?
For a child under 10 the finder favors light, low, simple telescopes and removes anything heavy, any equatorial mount and any optics that are hard to keep aligned. Refractors are sealed and need no adjustment, which suits young children. Tabletop reflectors give more aperture for the same money and are just as forgiving, provided the eyepiece sits at a comfortable height.
How much should I spend on a first telescope?
Enough for a stable mount and usable optics, which for most people means starting above toy-store prices. Under $100 buys real telescopes, typically 70 to 130mm, that show the Moon and Saturn's rings well, though at that price the tripod matters more than the optics. The finder works within whatever budget you give it and never suggests spending more.
Why does the finder never show a 100% match?
Every telescope is a set of trade-offs. More aperture means more weight. Motors add convenience but cost money and need power. No single design is best at both planets and faint galaxies. The finder caps its match score at 98%, even for a telescope that answers every question well, rather than claim a perfect match that does not exist.
