TS 2" Rack and Pinion RAP Focuser with SC Thread
The ultimate focuser for Schmidt-Cassegrain, EHD, ACF and Intes Micro telescopes with higher load capacity and accuracy than most conventional Crayford focusers we know of. We recommend this focuser especially to star enthusiasts who use their telescopes for observation and astrophotography and attach great importance to the highest rigidity and accuracy.

Note: The focuser only works on telescopes with at least 8" aperture, otherwise the focusing knob is too close to the thread to allow mounting.
