Product Details

  • 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.

Dead on tracking and pointing.

Easy to use and VERY accurate. Manual, precise polar alignment doesn't really take that long and with a high power reticle eyepiece very accurate. Doing high power solar and lunar I can walk away for half an hour and its still right on feature I was observing. I'm sure it would require little or no adjustment after an hour. Every thing high quality. Well worth the wait the recent wait.. I have two. One for 6" refractor and one for 14" SCT. Strongly recommend GPS unit. Adds significantly to accuracy and makes startup fast. Also dead centers Mercury, Jupiter and Saturn after sunrise and midday.

Good Combination of EQuipment

Delivery was as expected as to length, arrived undamaged and still in collimation. Mount is larger than expected, if you haven't seen the CGX-L in the field take a close look at the dimensions and weight. Breaks down into heavy, but manageable pieces. After a learning curve, the bundle works better than I expected.

Very Surprised

I was not expecting it until the end of January due to COVID slowing down or outright stopping supply chain activity. Actually received it before xmas! Also received the equatorial mount early, also slumbering in its shipping crate. I have not opened either box yet, as they are most safe where they are. Should probably open, inspect and re-seal both. Will be happy to review both when my concrete slab is poured, observatory (SKYSHED) is assembled, and we get to polar alignment, First Light, etc.

The price has gone thru the roof

What is being bought as an ota today, I received a cgem mount and ota for the same price in 2016

Better Than Expected

These counterweights are quite a bargain, concentrating a log of weight (10kg) into a single spot on the counterweight shaft. Excellent for 1.25" or 32mm applications. I used them on a 30mm counterweight shaft, by putting in a thin teflon sleeve made of adhesive teflon material. The finish is not "perfect", but is surprisingly good for counterweights from this source, and the knobs are easy to use and effective. There is a non-marring plastic tip on the securing bolt end.

Celestron 11” Edge HD OTA

Received this item in less than a week. It was double boxed and packaged extremely well. Once set up and aligned, this OTA is a quality upgrade from my 9.25” SCT. Planetary and nebula viewing is crash and clear. I can’t wait to start taking pics!
