Nice idea. A focusser is in my future once I get all the basics setup on my Bintel Newt. One of my outstanding questions is whether to try direct mount to the focusser shaft, or using a belt. A belt looks more attractive as I can’t find a coupler to match the 4.2mm shaft of my focusser. I was going to try and shim it out to the 5mm hole on the coupler I’ve ordered. But doing a belt instead would get around the sizing issue, it just more complicated to setup initially.

I’m waiting for the focusser parts to arrive from Fleabay China, but I didn’t order any pulley parts for the motor, just a flexible coupler. Do you need a toothed wheel on the motor shaft for this?
