Hi there, imaging people, and our resident "astro-history + NGC/IC" Guru who is otherwise known as glenc,
The region near NGC 3247 is NGC 3247 / RCW 49 /Westerlund 2
I am not going to sort out the exact Identifications here, as I am "not one of those fanatics who do that sort of thing",
but I do know Westerlund 2.
(note: the extreme Very Massive young star cluster Westerlund 1 "ain't got nothing to do with this", as it is in Ara!)
Westerlund 2 refers to the very compact and distant star cluster on one side of the nebula. This is a highly obscured ( 6 magnitudes of dimming due to foreground dust!) but very rich (some 7000 solar masses!) cluster which is a very severe test for amateur imagers and Deep Sky observers.
We are currently discussing Westerlund 2 in the observation reports forum:

Between me and Dana, I am sure that we could vastly improve the wikis on a lot of objects, but I don't contribute to Wikipedia because I feel that knowledge without attribution to a particular author is without value.
