Explore Scientific FirstLight 8" Dobsonian Telescope

Experience the Telescope That Changed Astronomy Forever! 

The Dobsonian revolution, sparked byJohn Dobson's  ingenious design, brought large-aperture telescopes to amateur astronomers everywhere. Before its introduction, most hobbyists were limited to small, primitive telescopes—barely capable of glimpsing Mars’ polar caps or Saturn’s rings. Larger telescopes, like Schmidt-Cassegrains, were the domain of the wealthy. Dobsonians transformed the game by combining simple, cost-effective mechanics with unparalleled light-gathering power, delivering incredible value and performance.

Explore Scientific’s Universal Design – A New Era of Versatility

We’ve reimagined the Dobsonian with cutting-edge features that make it a truly universal telescope. Need to capture stunning astrophotographs? Simply convert this Dobsonian into a Newtonian by removing the bearings and mounting the tube on an equatorial mount using the included Vixen-style dovetail plate. With this dual functionality, the sky isn’t the limit—it’s just the beginning!

Unrivaled Features for Unmatched Performance

• 2.5” HEX Focuser: Engineered for precision, its exceptional stiffness ensures effortless focusing with both 1.25” and 2” eyepieces. This premium component is a game-changer for telescopes in this price range.
