Does a larger Dobsonian show more?

More aperture gathers more light and can resolve finer detail in good conditions, though seeing, collimation and target brightness still matter.

Do I need an equatorial mount?

For visual observing, no. For long-exposure deep-sky astrophotography, an equatorial mount or field rotation correction is usually needed.

Are sunglasses safe for looking at the Sun?

No. Even very dark sunglasses are not safe. Use eclipse glasses that meet ISO 12312-2.

What type of telescope is best for beginners?

A 6 or 8 inch Dobsonian reflector gives the most to see for the money. A small refractor on a solid mount suits those who want grab-and-go simplicity.

Why trust AstronomyTested

Realistic expectations, every time

How we test
01Honest about the view

We describe what a telescope shows under real skies, not what the box art suggests.

02A clear verdict

Each guide says who the gear suits, who should look elsewhere, and what to check before you buy.

03No paid placements

Brands cannot buy a review or a spot on a list. Partner codes save you money; they never decide what we recommend.

04Kept current

Prices are dated, codes are updated across the site at once, and pages are revised when a product, standard or rule changes.
