Hi All,
I have been searching but cant seem to find what I thought would be relatively common given how clever amateurs are at making inexpensive but useful things.
Thanks to a new part manufactured by one of the local members of the local astronomy club, I now have everything working together on my Eon 110 F/6 refractor. The Adaptive optics, with the Flattener/reducer and the QSI583wsg. I can now get it all into focus, so I am really happy on that point. Thanks Les.
The last thing I want to achieve is adding some sort of electric focuser (without replacing the excellent rack and pinion focuser that is already on the scope).
I am sure I have seen somewhere, electric focusers that bolt or clamp on to an existing focuser and attach to the fine focus knob either by belt or some other means? But I cant seem to find any now that I want one

.
Is someone able to point me in the right direction?
I could probably make one myself as I have a 3D Printer and have a basic understanding of Arduino's but I am sure simple ones exist.
Thanks
TechnoBill
