Celestron 8" EdgeHD OTA with CGE Mount Plate
Item # CE-91030-XLT

* Required Fields

  • The Celestron EdgeHD 800 OTA is an aplanatic Schmidt telescope optical tube assembly designed to produce aberration-free images across a wide visual and photographic field of view.
  • Superior edge performance creates rounder, more pleasing stars and improves resolution and limiting magnitude when compared to telescopes of equal aperture.
  • The Celestron 8" EdgeHD OTA includes Celestron's StarBright XLT coating group on every surface for maximum light throughput across the widest visual and photographic spectrum.
  • The Celestron 8" EdgeHD optical tube produces a focal plane more than three-times flatter than standard SCT telescope and dramatically flatter than competing coma-free designs.
  • For a Limited Time, while Supplies Last, we will be including the C8EDG Model 'Bobs Knobs' Collimation knobs with this telescope at no additional charge! These knobs make Collimating your scope drastically easier, leaving the process far more efficient. See the video below for details!
  • OPT is offering a FREE Celestron Observer's Accessory Kit! A must-have for the new telescope owner looking for quality accessories for observing and basic Astro-Imaging with a DSLR camera.
  • This Kit includes:
  • Two high-quality Plossl eyepieces (6mm and 17mm) for high and moderate power viewing
  • Kodak Wratten #25 and #80A blue 1.25" eyepiece filters for increasing the contrast of planetary views
  • Neutral density Moon filter to increase contrast in lunar views by cutting back the birghtness of the image without changing its color
  • 3-in-1 Barlow/T-adapter, which can be used as a visual barlow, a basic T-adapter for connecting a DSLR camera, and a tele-converter for increasing the focal length of the telescope when attaching a DSLR camera
  • Microfiber lens cleaning cloth to keep your optics dust-free
  • Hard plastic carrying case holds all of these accessories with room for more of your own


Celestron EdgeHD 800 Aplanatic Schmidt-Cassegrain Telescope Optical Tube Assembly

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 Celestron first started producing Schmidt Cassegrain optical systems, they have continued to design high-quality optics with pride. After years of research and development, Celestron have now taken one giant step!

The Edge HD is Celestron’s latest innovation that will surely be the system of choice for the serious astro-imagers. The new Edge High Definition telescope series features an Aplanatic 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 astro photograph.

These superior features make the new Celestron HD series the new gold standard in Astro Imaging. The Edge 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.

Now let's talk about Celestron quality... 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. 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 throughput across the widest visual and photographic spectrum... It's a vision you'll never forget.

Celestron EdgeHD 800 OTA Features

  • 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.

  • 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.

i'v only had this ota a few days it is the perfect mate for my IEQ45 i attached the optional focal reducer and camera adapter and went to work i use a Nikon D3100 and the results were stunning all pics were under 60sec unguided single shots and they came out like a pro bright detailed images it's great when you show them to people to hear the gasps and ooohhs and aahhss from them. i tried to upload the pics but it doesn't seem to work i would have liked to show you. so the edgehd preformed' edge to edge all stars bright and round complete flat field i am really happy with this OTA i'm taking great astro pics..

Review by starhopper / (Posted on 8/23/2014)
Have owned many SCTs ranging from 5 to 14. Several have been of very high quality, but even on these scopes, I became increasinly aware of the shortcomings in off axis performance as compared to most refractors.

The EdgeHD changes that.

The 8 EdgeHD that I received was surprisinly beautiful. Picutures don't do justice to the paint, which is actually more of a metalflake finish than a pearl finish. The paint on my sample was beautifully applied as well. It looked more like a custom automotive finish than a typical telescope finish. I am impressed. It is simply far more handsome in person than pictures can convery.

In my initial tests, the edge of field performance is vastly improved as compared to standard designs. Even using wide field eyepieces, stars remain fairly sharp right to the edge of the field.

I have learned star testing by doing a lot of reading and testing a lot of telescopes. The 8 EdgeHD that I received had the best star test I have ever seen in a commercial SCT, being on par with some expensive European catadioptric scopes I have owned.

I have not had a chance to do prolonged testing, and my exposure has only been under less than great seeing, but my initial impression is that after searcing long and hard for the Perfect SCT, I believe I have found it.
