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.  


Priority shipping available also.  International shipping calculated at checkout. Please see the shipping tab for more info.
