My two pence worth…

surely it would be better to split off the backlash settings from the actual focusing algorithms given they are more to do with the focuser mechanics than how you work out how to do a curve to determine the best focal point?

Also looking at NINA that seems to have an idea of both in and out backlash compensation. Not sure whether you use both or just one. Which also brings me to in/out direction and sct’s, I’ve yet to try this out at night, but it looks like working in the in direction drops the mirror when really want it to be raising it. Maybe a switch would be of use for that, again maybe as part of the focuser mechanics.
