Product Description

Celestron CGEM 1100 Computerized Schmidt Cassegrain Telescope

 

TheCelestron CGEM 1100 Computerized Telescope features a high-end 11" Schmidt Cassegrain OTA with the famous XLT coatings mounted on our brand new CGEM™ mount. Ergonomic CGEM MountDesign The CGEM™ mount is not just a pretty face with its new and bold appearance. It is fully capable of carrying Celestron’s higher-end SCT optical tubes securely and vibration free. This makes it perfect for both imaging and visual observing purposes. 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. Ingenius Innovation The CGEM series aim to make things easier with the All-Star Polar Alignment procedure which allows you to choose any bright star in the sky, while the software calculates and assists with polar alignment. Another reason why the CGEM is great for astrophotography is the Permanent Periodic Error Correction (PPEC).This feature is meant to train out the worm gears periodic errors, while allowing for the mount to maintain the PPEC recordings. Great Performance For objects near the Meridian (which is 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.
