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).

SCT bracket note: As the focuser moves there is an internal screw that also travels in and out. The EAF bracket is designed to allow for some of this travel around the focus point, but does not allow for the full outward focuser travel. Prior to installing the bracket make sure the scope is roughly in focus.
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.
