About
A two-element cemented telecompressor developed to tame the focal length of Astro-Physics' 10-inch f/14.6 Mak-Cass and optimised for scopes from f/9 to f/18. It adds no coma, so it suits Maksutov-Cassegrains, Schmidt-Cassegrains, Ritchey-Chretiens and long-focal-length refractors, and screws onto any 2-inch nosepiece with 48 mm threads.
