Description

This was the first time I stacked the subframes I took that day and I inadvertently included some subframes with clouds. There are some weird artifacts from these mostly white frames. However, I can't seem to get the nice color rendition I get here without the bad subframes. Astro image capture and post processing is very strange because it is so unrepeatable. It's like painting, every time you paint the same thing, the final picture is something new. Everyone's version of M42 is different.
