The 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 40,000 objects, 400 user defined programmable objects and enhanced information on over 200
objects. Celestron's CGEM 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.
