Product Description

CELESTRON - C8-XLT 8" Schmidt-Cassegrain Computerized Telescope • 11026

The Celestron C8-SGT XLT Schmidt-Cassegrain Computerized Telescope is a very lightweight telescope that still maintains a remarkable light gathering power of 843x more than the human eye can see! In addition, it is also coated with StarBright XLT coatings to improve light transmission throughout the optical tube assembly, making this a very portable yet powerful Schmidt-Cassegrain optical tube.

The optical tube assembly is mounted on the Advanced GT mount that uses the NexStar computer control technology, including a database of over 40,000 celestial objects with information on over 200 of them. These include the planets and many of the famous deep sky catalogs as well. With the RS-232 and autoguider ports, the mount can be controlled and flash upgraded via the PC as well as control of a camera for astrophotography.
