A fresh update to the venerable CGEM mount, the CGEM II has a contemporary, attractive, bold appearance. The CGEM II is capable of carrying Celestron’s higher-end SCT optical tubes (up to 11") securely and vibration free, ideal for both imaging and visual observing. Capable of holding 18.2 kg (40 lbs) of payload and slews at 5° per second for instant pointing to any of the celestial objects in the database.

Ergonomic Design

CGEM II 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 II series features Celestron’s innovative All-Star Polar alignment procedure. All-Star allows you to accurately polar align the mount using any star, even when the celestial pole cannot be seen. Another great feature of the CGEM II sure to please astroimagers, is the Permanent Periodic Error Correction (PPEC) 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 II will track well past the Meridian for uninterrupted imaging through the most ideal part of the sky. The CGEM II mount has a robust database with over 40,000 objects, 100 user defined programmable objects and enhanced information on over 200 objects. Celestron's CGEM II mount is the perfect fit between the Advanced VX Series and CGX Series.
