2" Crayford Focusers for SCTs

These Crayford focusers supplement the SCT focuser that often
has backlash and causes image shift when focusing or tracking.
All four versions thread onto the male 2" SCT Schmidt threads
on the rear cell of the scope.

Thread on our Crayford focuser and enjoy smooth operation,
great feel and precise adjustability. The draw tube and unified
compression ring visual back are machined from solid aluminum
and anodized, and ride on precision bearings and a roller shaft.
No grease or plastic glides! The 1/8" thick-wall drawtube is
internally baffled and anti-reflection blackened.

The bodies are black anodized machined aluminum and have
tension and lock controls that adjust the focuser anywhere from
a very light feel to fully locked. Whether it's a light eyepiece or
a heavy camera, control is smooth and precise, with no image
shift, backlash, stickiness or bumpy feel.
