Tau Ceti X-Y Finder (TC-XY)
The Tau Ceti X-Y finder is used to offset a
guiding eyepiece or autoguider from the center
of the field-of-view (FOV) of a guidescope in
lieu of utilizing the traditional 3-point ring
mount. This allows the guidescope to be
held in place solidly and avoids
the potential for differential flexure.
Coupling is via standard 1-1/4" male and
female interfaces, or via M42 (T-thread)
interfaces for maximum stiffness.
The backfocus required is approximately 1-1/2".
Precise offsetting of the
autoguider or guiding eyepiece is via separate
x and y control knobs which allow +/-12mm of travel.
