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.
