Would love to see autofocus with full feedback,like the way centering works. I tried the current 2.5.1.17 version on my 8" Celestron Edge HD. I experimented with many different steps sizes, backlash values, etc over several days. Although I could get a "textbook" V shape, the focus was never as good as when using a Bahtinov mask. On my SCT, the mechanical backlash/hysteresis is not repeatable. If you have perfect focus at one value, it will be a different value when you try again a few seconds later. For a 30,000 center, this could be as much as +/- 50. Although only .2%, this is very noticeable in the images.
