Typically, you don't want to totally kill your background in astronomical images -- it looks more natural to have some background light, and there are usually faint structures buried there, whether that's other galaxies, streamers from the galaxy being imaged, etc. However, there was a really large amount of noise that had a weirdly large structure, and it was hard to reduce because of how close to the noise the galaxy was. So it's a darker background than I would normally like. However, I'm quite happy with the color I got in the galaxy!
