Barnard's Galaxy in Sagittarius. I only went after it because it's in the Caldwell Catalogue. I wan't impressed, either with the the object itself or the choice of it for the catalogue!
Why pick something with such a low surface brightness...? I wondered that about a number of objects in the Caldwell cat.
But the planetary nebula Shapley 1 is a fave, one of those smoke rings.
Worth the hunt.
