Celestron CGEM 1100 HD Aplanatic Schmidt Telescope 11082 Product Info

The Celestron CGEM 1100 HD Computerized Telescope 11082 combines the state of the art CGEM Computerized Equatorial Mount with the EdgeHD 1100 Optical System. With an optical tube assembly weighing only 28 lbs., this telescope by Celestron is still portable enough to be taken to dark skies, and has 89% more light gathering power than an 8" telescope and 40% more than the 9.25".  For astrophotography, the German Equatorial mount offers easier balancing, unlimited space at the rear of the telescope tube to mount a camera, and whole sky access. Now you can enjoy all of the NexStar software and database features with the extra stability and portability of a German Equatorial mount. These Celestron Telescopes feature an optical system that takes all of the compact power popularized by the Schmidt Cassegrain Telescope (SCT) and combines it with an improved High Definition Optical System for wide field, astrograph quality images. As a visual instrument, EdgeHD optics deliver pinpoint images even with your widest field eyepiece. You can search for all of the Messier Catalog objects, and see hundreds of other equally interesting NGC, IC and Caldwell objects with amazing clarity. For astroimaging, the EdgeHD optics produce aberration-free images across your favorite CCD or DSLR camera. All EdgeHD optics on the telescope are designed to produce an extremely flat focal plane precise enough to match the strict tolerances of the largest commercial ccd detectors, allowing all stars to be in tight focus to the very edge of the chip. The EdgeHD 11" optics produces a focal plane 3 times flatter than the standard equivalent SCT telescope with diffraction limited stars across the entire Nikon 300 or Canon 40D sensor!

Along with the EdgeHD optics, the Celestron CGEM 1100 HD Telescope has re-designed mechanics guaranteed to help you get the maximum performance from your instrument. The Celestron CGEM 11" HD Telescope features Mirror Locks that hold the mirror in place and reduce image shift during imaging. Also featured are Tube Vents, with each vent having an integrated 60 micron micro-mesh filter that allow hot air to be released from behind the primary mirror. All EdgeHD optical tubes are equipped with a removable secondary mirror for fast f/2 ccd imaging. Not only does imaging in the FASTAR configuration allow for exposure times that are 25 times faster than at f/10, but also yields a field of view five times wider.

Included with the Celestron CGEM 1100 HD Telescope 11082 is the CGEM Computerized Equatorial Mount. 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. The 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. The CGEM series has a new innovative Polar alignment procedure called All-Star. All-Star allows users to choose any bright star, while the software calculates and assists with polar alignment. Another great feature of the CGEM is the Permanent Periodic Error Correction (PEC) which allows users to train out the worm gears periodic errors, while the mount retains the PEC recordings. The CGEM mount has a robust database with over 40,000 objects, 100 user defined programmable objects and enhanced information on over 200 objects. The Celestron CGEM Mount is the perfect fit between the Advanced Series and CGE Series, offering the portability of the Advanced Series with the precision of the CGE.
