There's a lot to go over here... thanks BTW!
-What I'm doing is keeping HA//Oiii from doing any AF... since it doesn't seem to work well.
-Single start with a Sub frame is much faster than Full Frame. But I'll give the multi-star full frame a shot.
-I'll up the Step size for a try, but I've found when doing the Bahtinov mask it goes too far and I end up reducing the step to get it right. True AF bypasses that when fine tuning. You can see in the picture I have it stepped down gear-wise.
-Yeah that Linear-1 Pass looking promising.
-Backlash, I really tried checking for it and I see the knob moving with even 5 steps. So I've left it at 0. I should test with a step of 1.
