Feathertouch SCT MicroFocuser Compatibility

If your telescope is less than a few years old, check the style of the back cell to see which version of the SCT MicroFocuser you need.  If your telescope has a flat back (left picture), you need the standard C8 MicroFocuser.  If your telescope has a triangular pattern on the back (right picture), you will need the CPC version of the MicroFocuser.
