whenever I image a target that has a bright feature, like a galaxy core, autofocus will not work.
I image galaxies, clusters and nebula all the time. The only time I get issues with Focus is if my RCT is out of collimation. I initially had issues as, also coming from Maxim / FM, I was using exceedingly short AF exposures. I now use AF exposures around the 10-second mark and the problems went away.
