This is Messier 57 also known as the Ring Nebula as everyone knows. I only went with subs of 2-minutes maximum but I regret this as I noticed I was obtaining a ring of nebulosity outside of the ring. It is very faint but had I shot some longer exposures it would have shown up clearly. That is a challenge for another year. :-)
