I spent some time last night trying out the new routine. My gear is challenging - EdgeHD 14 at 2737mm. The routine still does not select donut stars for me. Oddly, for some of the more out-of-focus images, it would elect the Poisson spot at the center of the donut. It only selects real stars when they are tight enough to not show donuts, and then the HFR difference from step to step was not enough to make for a nice curve. I tried various binning settings and exposure lengths. I didn’t think to get screen shots of the curves, but I did get 10 focus packs for you to look at. I’m not sure how valuable they will be though, since in most cases, I canceled the focus run in just about every case when it was clear that it was going nowhere. For now, I’m going back to the old routine.
