Baader Alan Gee Telecompressors

The Baader Alan Gee Telecompressor is a focal reducer designed for Schmidt-Cassegrain telescopes and long-focus refractors, often used in front of a binoviewer or diagonal. It shortens the effective focal length to give a wider, brighter field without changing eyepieces.

This line includes the Telecompressor Mark II, the Universal 2" Telecompressor (UAG II), a centring ring for 9.25" SCTs and a 19mm M36.5 extension tube to fine-tune the reduction factor.
