The cocoon nebula. Had a string of usable nights for a change and decided to give this one a go.

Both pleased and fairly dissapointed with this one. I think the overall look is pretty respectable. But the lack of details in the dark clouds and around the nebula itself is a bit disheartening given the amount of data I collected.
