Celestron's CGEM-925 features our high-end 9.25 Schmidt Cassegrian OTA with XLT coatings mounted on our brand new CGEM™ mount.

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. 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™ (patent pending). 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) the CGEM 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 40000 objects 400 user defined programmable objects and enhanced information on over 200 objects.
