Description

First all-nighter at my favorite local darker sky site of the season! Unseasonably cold, but the skies were very good for AP. New flat panel I made works great!

LRGB gain and offset 75/12, -15C for you ASI1600 users.

Description: Fixed dark edge artifacts. They didn't jump out at me at first, but after a few hours away from the computer, I saw them.

EDIT- I don't notice this on my XISF or TIFF files, so I wonder if it's the JPEG compression??

Description: OK, tried a PNG file instead. Seems better. Perhaps I'm pixel-peeping too much. :-P
