Feather Touch® Micro Focuser with 10:1 reduction ratio for Celestron C-8 (NOT CPC/NexStar SE).

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 “C” Micro Focuser. If your telescope has a triangular pattern on the back, you will need the FTM-CPC8 CPC version of the Micro Focuser

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