Explore Scientific FirstLight 8-Inch Solid Tube Dobsonian Reflector Telescope — Outstanding Deep-Sky Views for Backyard Astronomers

The Explore Scientific FirstLight 8-inch solid-tube Dobsonian reflector telescope delivers outstanding deep-sky views for backyard astronomers. A Dobsonian is a Newtonian reflector on a simple, stable base you aim by hand — the best light-gathering value in astronomy — and this solid-tube 8-inch keeps the optics rigidly aligned in a rugged, easy-to-use package.

Its 203mm (8-inch) mirror gathers plenty of light for faint objects, and the 1218mm focal length (f/6) balances bright views with sharp detail on the Moon, planets, and deep sky.
