Micro Processor Controller for 9v Telecope Motor Focus Systems

This allows me to run my electric focusser without having to fight the controls in my handbox.The only reason for not giving it 5 stars is that it can only run from a 9V battery. I'd have loved to have been able to add an external power supply so that I could run it off the same 12v supply that runs the telescope. That aside, it works great.
