Buckeye Stargazer ZWO EAF-N and EAF-Pro Mounting Solutions
This bracket allows you to mount a ZWO Electronic Automatic Focuser (EAF) onto your telescope or lens focuser.
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).
See Technical Specification for Compatibility
As of June 2025 the EAF and EAF-Pro have a smaller pinion shaft than the original EAF (12v) and EAF-5v, as well as a USB-C connector. Please specify which Coupler will fit your particular EAF:
Coupler-EAF12v5v - fits the original EAF (12v) and EAF-5v
Coupler-EAFNPro - fits the newer EAF-N and EAF-Pro
