Celestron 11" EdgeHD OTA with CGE Mount Plate

Celestron’s 11-inch EdgeHD OTA’s built-in field flattener and optic design produce sharply focused, aberration-free and coma-free flat field views, which is ideal for serious astro-imagers. The EdgeHD ensures a flat focal plane all the way across to the edge of the field-of-view for optimal imaging, yielding high definition and pinpointing stars.

Edge HD optics help you not only capture rounder, more pleasing stars but improves its resolution and limit magnitude. When it comes to the Celestron EdgeHD series coupled with Celestron's StarBright XLT coating group on every surface, EdgeHD optics gives you maximum light across the widest visual and photographic spectrum... It's a vision you'll never forget!

 

Experience Better Imaging with the Celestron 11-inch EdgeHD OTA 

  • Mirror Support Knobs- Flexible tension clutches hold the mirror in place and reduce image shift when rotating the tube around the mount.
  • Tube Vents- Cooling vents located on the rear cell allow hot air to be released from behind the primary mirror. The vents are outfitted with an integrated 95-micron mesh filter.
  • Fastar Versatility- All EdgeHD optical tubes are Fastar compatible for imaging down to f/2 with optional accessories. 
  • Brighter Star Images- Light becomes more concentrated when focused precisely. This maximizes image brightness. 
  • CGE Mount Plate- Ready for attaching to your mount and tripod of choice.

Celestron C-11 Edge HD OTA

Great telescope, in my opinion better than the former Meade LX600 I used to own, which was much heavier, more difficult to set up and align, and confusion with the fork style mount. I much prefer a German equatorial mount.

Great OTA! It's a little heavier than I expected but has great views.

Never any doubt with Celestron

I've been a life-long owner of Celestrons, from an orange-tube C-8, a Great Polaris C-8, to an 11" Edge HD Schmidt, and I will never own another brand - don't need to, especially with the Edge's re-designed optics. I did some photographic work with a loaned Ritchey several years back, and in doing a side-by-side image comparison with Celestron's 11' Edge, I don't really see any differences - round stars to the edge, good definition, etc. Celestron has always paid great attention to their products.

Great OTA

Great views pinpoint to the edge. Mirror locks work well and ends mirror flop from meridian flip.. There is a slight amount of focus shift still present (moving secondary. Vents for cooling seem to work well. The scope came well collimated and has held it well. Have not been able to use the fastar option but is a nice bonus to have that option. the ota lives up to the hype in my estimation.
