ZWO EAF Mounting Solutions for Aftermarket Focusers


EAF Mount for Helical focusers

These brackets allows you to mount a ZWO Electronic Automatic Focuser (EAF)  onto Feathertouch, GSO, ZWO, QHY and Baader aftermarket  focusers.

The ZWO supplied M4 screws are used to attach the EAF to the bracket.  Where necessary a coupler is provided to connect the EAF pinion shaft to the focuser pinion shaft and is held securely with M3 set screws.  Note that the user will need to have a 1.5mm hex key for the M3 set screws (not provided).  


If you don't see a bracket that meets your needs I would be glad to work with you to come up with a solution.

Color Note:  The coupler will be black due to the special filament used for the coupler.  The bracket can be black, red or silver.
