Ok the object on the top left hand corner is NGC 3576-the object that Mike Sidonio (strongmanmike) imaged in the last issue of Sky and Telescope..my question is, what is the dark nebula down at the bottom?

also what resource do you go to to find answers to this sort of question? Barnard never looked this far south and I can't seem to find it any resource available to me
