Description

I didn't get as much of the dark nebula as I would have liked, but what can ya say for 3-minute subs under Bortle 7 skies? Also, the Ha made a huge difference. I processed a version without it (I'll add a link to the applicable blog post once I actually write it up), and wow what a difference it makes!
