CGEM II 9.25 EdgeHD

9.25” EdgeHD optics CGEM II computerized equatorial mount Celestron’s premium StarBright XLT coatings provide maximum light transmission A 9x50 finderscope, 2” mirror diagonal for more comfortable viewing, and wide-angle 23 mm Luminos 2" eyepiece are all included   Description True Astrograph Quality Many optical designs that advertise themselves as "astrographs" actually only produce pinpoint stars across a curved focal plane. While this may be acceptable for some visual observing, stars will appear out of focus at the edge when used with the flat chip sensor of a digital camera. EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. This guarantees you visibly sharp stars across some of the largest CCD chips available today. Individually Tested Every EdgeHD that ships has been tested not only for the surface quality of each optical component, but also with a camera and artificial star to ensure the imaging system meets our rigid quality assurance. This “final acceptance test” confirms the EdgeHD will perform in the field and deliver high-quality astroimages. MOUNT INFO A fresh update to the venerable CGEM mount, the CGEM II 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. Capable of holding 40 lbs. of payload and slewing at 5° per second, you will be able to instantly point to any of the celestial objects in the database.   FEATURES  40 lbs payload capacity Dual-fit Vixen/CG-5 and Losmandy/CGE dovetail saddle 2" steel legs with height index marks for quick leveling USB 2.0 port on hand control for direct links to a PC via ASCOM supported software 40,000 object database with over 100 user-definable objects and expanded information on over 200 objects Internal cabling throughout for worry-free remote operation Low cog DC Servo motor with integrated optical encoders offer smooth, quiet operation Able to track past the meridian allowing seamless imaging Permanent periodic error corrections allow users to train out the worm gears periodic errors once, while the mount retains the PEC recordings.
