Astro-Physics CCDT67 focal reducer (telecompressor) optimized for focal ratio between F/ 9 and F/18.
The 2-element cemented design transmits close to 99% of the incoming light over the range of 420 to 700 nm. The focal length of the telecompressor optics is 12". For refractors, the field is compressed by 0.67x. If you have a moving mirror system, plese
This focal reducer is not recommended for telescopes with focal ratio of less than F/9. For faster optics we suggests the use of the Astro-Physics AP-27TVPH 0.75x focal reducer.
