Explore Scientific 8" FirstLight Dobsonian Reflector


No telescope type has revolutionized the hobby quite like the Dobsonian. Prior to John Dobson's popularization of the Dobsonian telescope, most amateur telescopes consisted of small optical tubes with crude mechanics that allowed observers to see the polar caps of Mars or Saturn's rings at best. Schmidt-Cassegrain and other larger model telescopes were restricted to those with means. This innovative blend of simple but powerful mechanics with the largest possible opening gives the Dobsonian a unique place among telescopes. In terms of light gathering, no telescope offers as much bang for your buck as a good Dobsonian.

Explore Scientific has now introduced the preeminent universal design. This Dobsonian converts into a Newtonian telescope for astrophotography. To do this, simply unscrew the tube's bearings and attach the scope to an equatorial mount using the included Vixen style dovetail plate.

This package comes with an uncompromisingly rigid 2.5" HEX focuser with helical gearing and 10:1 reduction for easy focus. Enables the use of 1.25" and 2" eyepieces. The inclusion of the 2.5" HEX focuser is a vast improvement for telescopes in this price range.

Also included with the Explore Scientific 8" FirstLight Dobsonian are a 6x30 Finderscope and a 25 mm SPL eyepiece. FirstLight Dobsonians break down into as compact a package as possible for convenient transport. The rocker box can be disassembled with only a few tools since its components are put together with metal quick connectors. Therefore, a cumbersome rocker box quickly converts into a handy collection of flat boards. The optimal deep sky observing workhorse. Planetary and deep sky object detail will be apparent even for amateur viewers. Bright star clusters are resolved to the core, while viewing the lunar terminator line can be a rewarding experience.
