looks like a useful performance gain Peter.
Did a quick analysis of some of your unsaturated stars using Pixinsight (assuming the image data is not stretched). If I have the right pixel scale, the FWHM for the best fit Moffat PSFs went from about 6.2x5.5 arcsec down to 5.7x5.3 arcsec (ie AO mainly tidied up the star roundness). The peak signal went up by ~10%, as you found, so I guess no stretching.
But 5+ arcsec seems to be really bad seeing - I assumed 1.6 arcsec pixel scale, is that right?
