AF in 2.4 has been nothing but a huge headache, so much that I can’t let my sequences run unattended for fear of the system totally screwing the focus. I’m having problems now that I didn’t have before and can’t seem to dial in the settings, especially the sample size. Running at full sample size produces nonsense so I pull down to 15 and get somewhat better results, however the results are still not stable and if the test doesn’t produce a nice “V” curve it just keeps on trucking and keeps moving the focuser, somehow believing that true focus is 1,000 steps from where we started. What takes the cake is tonight I cancelled an AF run that had lost its mind and before the focuser could return to starting position the next frame started integrating.
I usually run 7 data points with 100 steps each @ 4s exposure ISO 800 but I’ve tried lowering ISO and increasing points to no avail. I’m running 188.8.131.52.
I’m hoping this is just user error, but I’m getting wings on my curves and things are generally a hot mess for anything I try to do with AF. Confidence is low.
BTW, I’m trying to image Leo’s Triplet, so maybe I’m just in a bad part of the sky…
Here are some AF packs:
