EAF Bracket for the ZWO Helical Focuser

An EAF Bracket for the ZWO Helical Focuser is the latest accessory available from the Buckeyestargazer Shop. Joel Short, an astroimaging enthusiast located in Northern Indiana, opened the Buckeyestargazer Shop to make available items he has developed to offer affordable and uncomplicated accessories. As Short comments, “These are simple and practical items that I have found to be essential for amateur astronomers.”

EAF Bracket for the ZWO Helical FocuserAs Short notes about the EAF Bracket for the ZWO Helical Focuser, “The ZWO 1.25″ Helical focuser is a popular focuser that is commonly found on the ZWO OAG and comes in two varieties: one with a female M42 threaded mount and one integrated into the OAG. The M42 version can also be used on camera lenses. This mounting bracket allows a ZWO EAF to be mounted on the Helical focuser for precise automatic focusing. The bracket is 3D printed with carbon fiber PETG filament and uses a belt drive system for zero added backlash. Full installation instructions and operation notes are also provided.”

Short also comments, “1.25-inch cameras and cameras up to 78mm in diameter can be used in the Helical focuser with the bracket in place – this has been tested with 1.25” cameras and “planetary” cameras with a diameter of 62mm (78mm dia. cameras with a 1.25” nosepiece should work, but are untested). For the M42 version, the radius of the bracket extends 10mm from the red M42 ring. For the OAG version, the radius of the bracket extends 12mm from the OAG red bottom ring.”
