Description

Love the results I got from this stack. I almost gave up on it because the focal reducer was killing the image with terrible donuts, but with aggressive background extraction and heavy mask usage, I got a ton more out of the actual nebula than expected. This target is much less nuanced in the visible spectrum, but I still love the details that I could get with the appropriate masks.
