Celestron EdgeHD Telescopes

Celestron EdgeHD is an aplanatic Schmidt-Cassegrain design that adds corrector lenses in the baffle tube to deliver a flat, coma-free field across a camera sensor. This collection includes EdgeHD 8", 9.25", 11" and 14" optical tubes, complete kits on Advanced VX, CGEM II, CGX, CGX-L and NexStar Evolution mounts, and dedicated accessories.

Look here for the 0.7x reducer lenses for EdgeHD 800, 925, 1100 and 1400 and the matching T-adapters with the correct back focus for imaging.
