  • Flexible tension clutches hold the mirror in place and reduce image shift when rotating the tube around the mount
  • Cooling vents located on the rear cell allow hot air to be released from behind the primary mirror
  • All EdgeHD telescope optical tubes are Fastar compatible for imaging down to f/2 with optional accessories

Product Description


Celestron's innovative new EdgeHD telescopes are aplanatic Schmidt Cassegrain models designed to produce aberration-free images across a wide visual and photographic field of view. Celestron EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt Cassegrain telescope. This guarantees you visibly sharp stars across some of the largest CCD chips available today. Superior edge performance not only creates rounder, more pleasing stars but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture. With Celestron's High Definition optics you will be able to capture the faintest of galaxies all the way to the corner of your full frame camera chip. Coupled with Celestron's XLT coating group on every surface, EdgeHD optics gives you maximum light throughput across the widest visual and photographic spectrum. The EdgeHD tube has been redesigned with top-notch features to make sure you get the most from your optics each and every night. Mirror locks hold the mirror in place and reduce image shift when rotating the tube around the mount. Flexible rods allow the mirror to be held in place without putting any force or pressure on the mirror, keeping the image centered in the eyepiece (or chip). Cooling tube vents located on the rear cell allow hot air to be released from behind the primary mirror. Each vent has an integrated 60 micron mesh filter guaranteed to let warm air out without letting dust in.

5Celestron EdgeHD 800 CGEM
By B. Wells
I have only begun using this telescope, but so far, it has been flawless to setup and to operate. The quality of the Optical Tube Assembly (OTA) is top notch and the quality of the German mount is also excellent. Once fully assembled, the scope is heavy and between setting up and aligning; you will be looking at least an hour and maybe 2 hours to get it ready to go from soup to nuts. So ideally, you can set this up in a location where it does not have to be torn down and re-set up every time you want to use it.

My interest is astrophotography, and I began my search for the right equipment at the astronomyforum.net. In the end, I shopped at the following locations to purchase the following gear:
