Astro-Physics CCD Tele Compressor CCDT67 – 0.67x Reducer – 85mm working distance

The Astro-Physics Tele Compressor was originally developed for telescopes with an aperture ratio of f/9 or higher. However, practical tests have shown it to be excellently suited to GSO’s RC telescopes. Stars are imaged very sharply within a 29mm diameter area.

When using an SLR camera, this focal adapter ensures the correct distance: there are still 55 mm remaining to the camera sensor. This is the distance required by standard DSLRs when used in combination with a T2 ring.
