Another breezy evening so very few usable frames last night.  I did manage to get an improved M51 so I’ve updated my Messier list, but my M57 is about the same as the one I already had and M63 and M64 had too few frames to stack.

You can see from the M51 image here that Amp glow is starting to become an issue. This image was made with 17×60 second exposures taken from an AVI with 46 frames. That’s a lot of wasted time and effort, I think some were spoiled by the PE rather than the weather, so at least I can do something about that.

M57 was taken from a stack of 42x18second exposures, however less than 20 were usable. Dropping the gamma and gain seems to help keep the backgrounds dark. I must make an effort to record the values I use for all the sliders.
