I forgot to mention in my last post that the night was cut short by smoke. I don’t know where the fire was or how large it was, but it devastated the seeing with atmospheric particulate. I had to cut the evening short due to this, but tried to get Messier 33, the Triangulum Galaxy, before it got too bad. I also took some subs of M45, but this weird optical issue made the Pleiades shots unusable. That will be great target to shoot again another time. The noise/vignette one-two punch strikes again! I am going to get this sorted. Seriously.
