What Telescope Should I Get?
The most-asked question in astronomy, answered without the hype. This is an educational guide — no affiliate links, nothing to sell. Just how telescopes actually work, what matters (and what doesn't), and how to match one to your budget, your skies, and what you want to see.

For most people: an 8-inch Dobsonian
If you want one honest recommendation to start from, it's a 6- or 8-inch Dobsonian reflector. It gives you the most light-gathering power for your money, it is genuinely simple to point and use, and it will show you the Moon's craters, Saturn's rings, Jupiter's moons, star clusters, and the brighter galaxies and nebulae. An 8-inch typically runs about $700–800 (a 6-inch less); the Apertura AD8 and the Sky-Watcher Classic 8" are the usual reference points. Below is why — and how to choose differently if a Dob isn't right for your situation.
Orion Telescopes & Meade ceased operations in 2024 — you'll still find their old scopes secondhand, but there's no company behind them now. Active, reputable makers include Celestron, Sky-Watcher, Apertura, and Zhumell. This guide names examples for orientation only; it doesn't sell or link to any of them.
Aperture, not magnification
The single most important number is aperture — the diameter of the main lens or mirror. Aperture is how much light the telescope collects, and light is what lets you see faint, distant things and fine detail. A bigger aperture beats a bigger magnification every time. That's why the honest advice is "buy the most aperture you can comfortably afford and carry."
The number the box shouts about — "600x magnification!" — is close to meaningless, and is the surest sign of a scope to avoid. Useful magnification is capped by aperture and by the shimmer of Earth's atmosphere; in practice you rarely exceed about 50× per inch of aperture, and often much less. A tiny scope cranked to 600× shows a dim, blurry blob. The three telescope types below all gather light differently, but the rule holds for all of them.

Five questions that pick your scope
- Budget? Under ~$150, buy binoculars, not a telescope — a cheap scope will disappoint. Around $300–800 is the beginner-telescope sweet spot.
- Can you lift and store it? An 8-inch Dob is bulky (think a big kitchen bin). Tight on space or strength? Drop to a 6-inch or a tabletop scope.
- What do you want to see? Moon and planets look great in almost anything. Faint galaxies and nebulae need aperture and dark skies.
- How dark are your skies? Dark rural skies (which you have near St. Cloud) reveal far more than any gear upgrade under city glow.
- Do you want it to find things for you? Computerized "go-to" and phone-guided (e.g., Celestron StarSense) scopes cost more and trade some aperture for convenience.
| Your situation | Good starting point |
|---|---|
| Most beginners, want the best views for the money | 8-inch Dobsonian (e.g. Apertura AD8, Sky-Watcher Classic 8") |
| Limited space / strength / smaller budget | 6-inch Dob or a tabletop Dob (e.g. Sky-Watcher Heritage 130P/150P) |
| Kids, grab-and-go, travel | A tabletop Dob or a small refractor — or start with binoculars |
| Totally unsure / smallest budget | A good pair of 10×50 binoculars |
| Want it to find objects automatically | A go-to or phone-guided scope (e.g. Celestron StarSense) — expect less aperture per dollar |
The rest of the guide
Telescope Types
Refractor, reflector, Dobsonian, and compound (SCT / Maksutov) — how each works, with light-path diagrams, and who each one suits.
Start With Binoculars
The best-value first step in astronomy — why a $60 pair of 10×50s is never a wasted purchase, and what they'll show you.
How to Actually Observe
Dark adaptation, finding things, realistic expectations vs Hubble photos, and staying warm on a Minnesota night.
How not to waste your money
"600x magnification!" — the classic red flag. Magnification is limited by aperture and air, not marketing. Ignore the number; look at the aperture and the mount. The department-store refractor — a thin tube on a flimsy, wobbly tripod is the most common bad first telescope; every touch sets the image shaking. "Bigger is always better" — only if you'll actually carry it outside; the best telescope is the one you use, so an 8-inch that stays in the closet loses to a tabletop scope you grab weekly. And remember the view is not a photo: those glowing Hubble nebulae are long-exposure images in false color — through the eyepiece, deep-sky objects are mostly soft grey smudges, and that's normal (see how to observe).
