Hi Andrew,
Yes, Feather Touch focuser are like a Rolls Royce. I have looked at them earlier and belive it must be perfect in precision and it has rack and pinion too.
I think this model best fit my needs:

But one problem, the threads doesn't fit my telescope or my field flattener.
M120 inlet compare to my M92 and M86 outlet compare to my M80. If I connect them the thread adapters will take some space, maybe it still could work.
For the moment I think I try to get the most out of what I have.
Thank you to remind me about Feather Touch as an option!
