DIY Autofocuser...recommendations needed please


Recommended Posts

Hi All,

I've been searching and have discovered many snippets of info of people designing and building their own USB auto focusers and was wondering if this is something I could make for my Startravel 102 scope which uses a rack and pinion focuser. I have a 3D printer pretty much sitting doing nothing and am quite handy with a soldering iron. What I'm very very bad at is designing and coding so am looking for pointers to someone that has published a DIY kit I can make. Could anyone help? As I'll be using it with NINA it must be ASCOM compatible (or is that INDI as well?).

Thanks guys. I'm going to chomp through a document Robert Brown kindly emailed over and see. The biggest problem I see at the moment is the physical mounting of it to the ST102 scope and how / if it can connect to either the knob or bar of the focuser. Have any of you any thoughts on this / done this on a similar scope / focuser?
