Celestron EdgeHD 800 OTA with CG-5 Dovetail Plate

The Celestron EdgeHD 800 OTA with CG-5 Dovetail Plate is an aplanatic (Corrected) Schmidt telescope designed to produce aberration-free images across a wide visual and photographic field-of-view. 

Highlighted Features of the Celestron EdgeHD 800 OTA

Improved Performance

With StarBright XLT Coating groups on every surface, EdgeHD optics give you maximum light throughput across the widest visual and photographic spectrum. Produce images with improved resolution and rounder stars!

Mirror Clutches 

Flexible tension clutches hold the mirror in place and reduce image shift when rotating the tube around the mount. The flexible rods allow the mirror to be held in place without putting any force or pressure on the mirror assembly, keeping the image centered in the eyepiece (or chip).

Tube Vents 

Cooling vents located on the rear cell allow hot air to be released from behind the primary mirror. Each vent has an integrated 60 Micron micro-mesh filter guaranteed to let warm air out without letting dust in.

Fastar Versatility 

Achieve the image scale necessary to capture the smallest of deep-sky objects! With an optional reducer lens, you can increase your field-of-view without sacrificing optical performance. A Barlow lens gives you the added power for high-resolution planetary, lunar, and solar imaging. Each tube has been fitted with a removable secondary mirror and is optomechanically aligned on a laser bench to ensure they are axially symmetric in any configuration.

Note: Included with the OTA is a Dovetail Plate for attaching it to your mount.  This plate is CG-5 compatible.
