SpaceCat 51 Autofocus

May 9, 2020

Another autofocuser configuration I'm trying out with the William Optics SpaceCat51 and the Deep Sky Dad AF3 stepper and focus ring. The goal is portability, and I have the motor and controller bolted to a guide-scope shoe that can be easily added or removed from the scope. I 3D printed a tension adjustment bracket--that's the gray half-cylinder piece on the opposite side of the handle.
