This is mainly due to that the 100ft wires were too flimsy to last and secondly that I can then precisely control the focus, even without a focuser program.

The core of the focuser is an arduino…

Turns out that the focuser cable could be 100 ft long and still work.

Then I noticed that my Celestron hand controller had the same 6 pin RJ11 port. I thus…
