Does anyone know how far the focus point moves vs 1 rotation of the focus knob? I’m trying to focus my ZWO120 guidecam on an Orion TOAG with Canon 1200D primary cam, and the guide focus is off by about 1/10th of a turn of the focus knob. Celestron 6SE. I can probably work it out with more testing, but I thought I’d ask. Cheers.
