I have tried other algoritmes but with no effect.
My focusser goes from 0 (full inward) to 100000 (full outward).
When i go to 50000 thru Ekos where my infocus normally was and i try autofocus then i eventually end up around 10000.
Then when i look at my focusser then i see the focusser at around 40000!!! So i thing it must be something like slippage.
I wil look at it today and hopefully i can image tonight.
