TS 2" rack and pinion RAP focuser with SC connection thread
An ultimate focuser for Schmidt-Cassegrain, EHD and Intes microtelescopes with higher load capacity and accuracy than most conventional Crayford focusers we know of. We recommend the focuser primarily to astronomers who use their telescope for observation and astrophotography and value maximum rigidity and precision.
Caution: The focuser only works on telescopes with an aperture of at least 8", otherwise the focus knob is too close to the thread to allow assembly.
