Description

The Crescent Nebula, mostly in hydrogen-alpha. I got a tiny bit of oxygen but the sulfur signal was so weak that I didn't even include it. I ran 88 minutes of RGB just for the stars, composited that in, and called it good. This was actually shot over four nights, with a bright Moon for the narrowband and a new Moon for the RGB.
