Feather Touch® Micro Telescope Focuser for Celestron CPC-1100, C11 EdgeHD Schmidt-Cassegrain Telescopes.

Is this the Correct Focuser for your Telescope:

If your telescope is less than a few years old, check the style of the back cell to see which version of the Feather Touch® SCT Micro Focuser you need: If your telescope has a flat back, you need the standard FTM-C11 C11 version of the Micro Focuser. If your telescope has a triangular pattern on the back, you will need the CPC version of the Micro Focuser.

Feather Touch® Micro Focusers can be motorized using the optional HSM-20 Handy Stepper Motor.
