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 percent more light that the 9.25-Inch EdgeHD, and 89 percent more than the 8-Inch. At 28 pounds, this OTA is still portable enough to take out to your favorite dark sky spot.

 

Introducing the EdgeHD Telescope Series, Celestron's new flagship telescope line...
Celestron has taken another bold step as the market leader in telescopes with the introduction of their latest series of high-end telescopes. Since the moment they first started producing Schmidt-Cassegrain optical systems, Celestron has continued to design high-quality optics with pride. After years of research and development, they have now taken one giant step!

The EdgeHD is Celestron's latest innovation that will surely be the system of choice for the serious astroimagers. The new Edge High Definition telescope series features an aplanatic (corrected to be free of aberrations) Schmidt optical system that produces pinpoint star images all the way to the edge of the field. Some optical systems currently on the market may produce coma-free images. But there is a difference.... the optical difference. Not only is the Celestron EdgeHD coma-free, but it also has a built-in field flattener to ensure sharp focus all the way to the edge of the field, producing true Astrograph quality images. This results in pinpoint, High Definition star images throughout your astrophotographs.

These superior features combined with our recently introduced CGX and CGEM-II mounts make the new Celestron Edge series the new gold standard in astroimaging. The EdgeHD is an aplanatic Schmidt telescope designed to produce aberration-free images across a wide visual and photographic field of view. The optical system was designed to reduce more than just off-axis star coma, but also to give an astrograph quality flat focal plane all the way to the edge of the field of view.

Many optical designs that advertise themselves as astrograph quality actually only produce pinpoint stars across a curved focal plane. While this may be acceptable for visual observing, stars will appear out of focus at the edge when used with a 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 other competing coma-free designs. This guarantees you visibly sharp stars across some of the largest CCD chips available today.


The Celestron CGEM-II mount has a fresh, attractive, bold appearance and is capable of carrying Celestron's higher-end SCT optical tubes (up to 11-Inch) securely and vibration free which is ideal for both imaging and visual observing.

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 - The Celestron CGEM-II 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 91526, sure to please astroimagers, is the Permanent Periodic Error Correction (PEC) which will allow users to train out the worm gears periodic errors, while the mount retains the PEC recordings. Furthermore, a new dual saddle has resulted in this stellar mount having 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 91526 mount has a robust database with over 40,000 objects, 400 user defined programmable objects and enhanced information on over 200 objects.

Celestron's CGEM-II mount is the perfect fit between the Advanced Series and CGE Series. Offering the portability of the Advanced Series and the precision of the CGE.

Superior mount performance combined with superior edge performance not only creates the rounder, more pleasing stars but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture. When it comes to the Celestron HD series coupled with Celestron's StarBright XLT coating group on every surface, EdgeHD optics gives you maximum light throughput across the widest visual and photographic spectrum... It's a vision you'll never forget.
