Feather Touch^® Micro for Celestron C-11 Schmidt-Cassegrain Telescope (NOT CPC1100)

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 (left picture), you need the standard "C" Micro Focuser. If your telescope has a triangular pattern on the back (right picture), you will need the "CPC" version of the Micro Focuser.
