CELESTRON - C6-SGT 150mm Schmidt-Cassegrain 6" Computerized Telescope

The Advanced C6-SGT is a f/10 1500mm Schmidt-Cassegrain optical tube that features a precision optical system that has 40% more light gathering power than a 5" telescope. With the addition of the StarBright XLT coatings on the optics, light transmission is also improved greatly!

The Advanced GT computerized mount uses NexStar computer technology that include a 40,000 objects database and information on over 200 of those. This includes the planets as well as many famous deep sky catalogs like the Messier list. With the RS-232 port on the hand controller, the Advanced GT mount can also be controlled via the computer and updated by flash upgradeable systems. For astro-imagers, there is also an autoguiding port.

The Celestron German Equatorial mount has precision worm gears on both axes for extremely smooth stability.  The key element that makes this system the most stable in its class is the heavy-duty tripod with larger and more substantial legs that offer excellent damping characteristics for more stable views.  The CG-5 also has a convenient latitude scale for easier alignment and an optional polar finder scope for the ultimate in precision alignments.
