Maybe I'll try some shorter exposures to throw in the mix. M31 was the
last subject I shot and the camera has not been rotated.

It's fresh SHQ200. PF at f/8. My longest shot in this sequence would be
roughly equal to a 70 min shot at f/4. That doesn't seem out of line to
me. Skies are pretty dark, autoguider,...
