Celestron EdgeHD OTA

The EdgeHD design features a built-in field flattener lens, which eliminates off-axis coma and field curvature. This results in pinpoint stars all the way to the edge of the frame, making it significantly better for astrophotography with large-sensor cameras.

No, this is an Optical Tube Assembly (OTA) only. It includes a CGE-style dovetail plate for mounting, but you will need to provide your own compatible equatorial mount and tripod to support the 28-pound weight of the tube.

Yes, the system is Fastar compatible, which allows you to remove the secondary mirror and attach a camera at the front of the telescope. This converts the system to an f/2 focal ratio, providing a much wider field of view and faster exposure times for deep-sky imaging.

The EdgeHD 11-inch has a back focus distance of 146.05mm from the rear cell threads. This generous distance allows plenty of room to attach accessories like off-axis guiders, filter wheels, and various camera adapters.

Absolutely. While it is optimized for astrophotography, the 11-inch aperture provides exceptional light-gathering power for visual observation. It includes a 2-inch diagonal and eyepiece, making it ready for high-resolution planetary and deep-sky viewing right out of the box.

Like any high-end telescope, you should keep the optics covered when not in use to prevent dust accumulation. The StarBright XLT coatings are durable, but you should only clean the lenses when absolutely necessary using proper optical cleaning solutions and microfiber cloths to avoid scratching.
