The Celestron CGEM II is a medium capacity GO-TO equatorial mount with a payload of 18kg, ideal for carrying Celestron's mid-sized Schmidt-Cassegrain telescopes (up to 11" for visual). The 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. 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 if the celestial pole cannot be seen. Another great feature of the CGEM II 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. 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 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. The CGEM II includes a dual saddle plate that accommodates both CG-5 and CGE-style dovetail. Switching between the two saddle plates is as simple as moving the hand knobs into a separate set of holes. Note: Compatible with Vixen format dovetails 100mm or longer, not compatible with Losmandy D format plates (regardless of plate manufacturer).
