I think every man and his dog had a go at imaging M20 at Astrofest. I was only there 2 nights, and the first night was plagued with equipment issues, and this ended up being the only DSO I captured. The only other thing I came away with was
some star trails.
I think this is my best image to date, and first hard-core go at LRGB processing with the QSI583. I particularly wanted to bring out the dusty bits, and pay special attention to the noise. There are a couple of artifacts in there that I might play with later, but all in all I'm extremely happy.
In processing this, I've made a huge list of questions about LRGB image processing, so expect to be bombarded shortly.
Any and all comments and advice welcomed.
Repro (hopefully) incorporating H's suggestion added.
