Celestron's CGEM-1100 telescope offers premium performance and mobility for stargazers seeking the ultimate Astronomy experience. It features an 11" Optical Tube weighing only 27.5 lbs., and a telescope mount with a unique ergonomic design for ease of use and convenient mobility. Equipped with StarBright XLT coatings it can capture up to 89% more light gathering power than an 8" telescope. The CGEM-800 Equatorial mount 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 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 alow 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 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 obects and enhanced information on over 200 objects.
