Celestron CGEM 800 8" Schmidt Cassegrain Computerized Telescope

The Celestron CGEM-800 Telescope features the high-end 8" Schmidt Cassegrian OTA with XLT coatings mounted on the Celestron CGEM Computerized Equatorial Mount. These Celestron Starbright XLT Coatings give you the Extra Light Transmission needed when imaging deep sky objects.

The Celestron CGEM Mount has a fresh, attractive, bold appearance and is capable of carrying Celestron 's higher-end SCT optical tubes (up to 11") securely and vibration free which is ideal for both imaging and visual observing. The Celestron CGEM Computerized EQ Mount is the perfect fit between the Advanced Series and CGE Series, offering the portability of the Advanced Series and the precision of the CGE.

Ergonomic Design - CGEM was designed to be ergonomically friendly with large Altitude and Azimuth adjustment knobs for quick and easy polar alignment adjustment. The internal RA and DEC motor wiring provides a clean look and an easy and trouble free set up.

Innovation - The CGEM series has a new innovative Polar alignment procedure called All-Star. All-Star allows users to choose any bright star, while the software calculates and assists with polar alignment. Another great feature of the CGEM, sure to please astroimagers, is the Permanent Periodic Error Correction (PEC) which will allow users to train out the worm gears periodic errors, while the mount retains the PEC recordings.

Performance - For objects near the Meridian (imaginary line passing from North to South), this Celestron Telescope will track well past the Meridian for uninterrupted imaging through the most ideal part of the sky. The CGEM mount has a robust Database with over 40,000 Objects, 400 user defined programmable objects and enhanced information on over 200 objects.
