Celestron CGEM-II 1100 EdgeHD f/10 Modified SCT Catadioptric Telescope

The CGEM-II 1100 EdgeHD Telescope by Celestron is a 279 mm (11-inch) Aperture corrected flat-field Schmidt-Cassegrain telescope with a CGEM II computerized German equatorial mount atop a sturdy tripod.  This 11-inch EdgeHD optical system gathers 40% more light than the 9.25-inch EdgeHD and 89% more than the 8-inch. At 28 lb, this OTA is still portable enough to take out to your favorite dark sky spot.

CGEM-II 1100 EdgeHD Features 

Ergonomic Design - The Celestron CGEM-II 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 provide a clean look and an easy and trouble-free set-up.

Innovation All-Star allows users to choose any bright star, while the software calculates and assists with polar alignment. Its Periodic Error Correction (PEC) allows users to train out the worm gears periodic errors, while the mount retains the PEC recordings. Furthermore, its dual saddle has the capacity to mount either CGE-Pro style Dovetails or CGE-5 Dovetails.

Performance - For objects near the Meridian (imaginary line passing from North to South), the Celestron CGEM mount will track well past the Meridian for uninterrupted imaging through the most ideal part of the sky. The CGEM-II mount has a robust database with over 40,000 objects, 400 user-defined programmable objects and enhanced information on over 200 objects.

Included Technology

All-Star Polar Alignment

Get ready for a night of astroimaging with your mount faster than previously thought possible with All-Star Polar Alignment. This innovative software solves the time-consuming problem of trying to pinpoint the North Celestial Pole.

EdgeHD Optics

Celestron’s aplanatic EdgeHD optics revolutionized astroimaging. This award-winning optical system reduces visual defects like field curvature and coma, creating an ultra-flat field for pinpoint stars all the way to the edge of today’s largest imaging sensors.

Compatible Technology

LiFePO4

The new Lithium Phosphate (LiFePO4) battery chemistry has significant advantages over other battery chemistries, great for those Astronomers on the go.

Starsense Technology

Celestron’s patented StarSense Technology makes it easier than ever to locate objects in the night sky, even if you’ve never used a telescope before. Turn it on and push ‘Align.’ In about three minutes, you’re ready to observe!

WiFi

WiFi technology encircles the globe in a web of connectivity, knowledge, and information. Now, Celestron is using that same technology to allow stargazers to connect to the night sky and enhance their experience of the cosmos in fun and unique ways.
