These are the necessary parts to adapt a [Nema17 PG5 stepper](https://www.omc-stepperonline.com/nema-17-stepper-motor-bipolar-l-33mm-w-gear-ratio-5-1-planetary-gearbox-17hs13-0404s-pg5) to a common Sky-watcher crayford focuser.

The controller is a stripped down implementation of [myFocuserPro2 ](https://sourceforge.net/projects/arduinoascomfocuserpro2diy/) using only an arduino nane, a stepper motor module, a standard 12v power connector and a bit of soldering.
