EAF Bracket for Feathertouch Micro Focusers

Now includes couplers for both the original EAF (5mm shaft) and the new EAF (4mm shaft).

Starizona's EAF Bracket for Feathertouch Focusers allows you to attach a ZWO EAF autofocus motor to a Feathertouch SCT MicroFocuser or to a Feathertouch 2" Crayford focuser.

The bracket is machined from aluminum and includes a custom flexible shaft collar.  It attaches to the coarse-focus adjustment of the Feathertouch to avoid slipping and uses the very high resolution of the EAF to provide a fine step size.  On a Feathertouch SCT MicroFocuser, the step size is 0.14 micron.  On a Feathertouch 2" Crayford focuser, the step size is 3.4 microns.
