Best Dobsonian Telescopes for Beginners (2026)
If you want the most aperture for your money, a Dobsonian is the answer. It's a Newtonian reflector on a simple alt-azimuth mount — basically a tube on a rotating box. No fancy electronics, no complicated tracking. Just big optics on a simple, stable base.

Check Price →What Size Dobsonian?
Dobsonians come in 4", 6", 8", 10", and larger. Here's how to choose:
6" (150mm) — The Sweet Spot
Shows you the moon, all the planets, and dozens of deep-sky objects. Portable enough to carry to a dark sky site. The most popular beginner size for a reason.
8" (200mm) — Step Up
Significantly more light-gathering power than 6". You'll see more detail on planets and fainter deep-sky objects. Heavier, but still manageable for one person.
10"+ — Serious Hobbyist
These are big. You'll see things you didn't know existed. But they're heavy, bulky, and require a permanent spot in your house. Only go this big if you're sure you'll stick with the hobby.
What About Collimation?
Reflectors need occasional collimation (aligning the mirrors). Don't panic — it's not as hard as it sounds. A Cheshire eyepiece or laser collimator makes it a 5-minute job. Most Dobsonians come pre-collimated from the factory, and they hold alignment well for months.

Frequently Asked Questions
Is a Dobsonian good for beginners?
Yes — Dobsonians are actually one of the best choices for beginners. The simple alt-az mount is easy to use, and the big aperture gives you great views. The only downside is you need to learn your way around the sky (or use an app like StarSense).
What size Dobsonian should a beginner get?
6" is the sweet spot. It's big enough to show you amazing things, but small enough to carry around. If you're short on space or budget, start with a tabletop model.
Can you astrophotograph with a Dobsonian?
Not really — Dobsonians don't track the sky. You can take afocal photos of the moon and planets, but deep-sky imaging requires a tracking mount.
