first off thanks Glen, Les and Rob and others for a very nice read in this thread. I like globs a lot.
This is a bit embarrassing to post after the SteveG excellent observation but in the spirit of answering the question who has seen Ngc6749 and in what conditions, here goes
From 2700 feet at lat +36 (central California, USA) with SQM 21.0 (not real dark) in an 18" dob at 188x. This was in 2008 and I promise that since then I have improved a lot in my observational details
. So this one is worth a re-visit this summer.
No resolution, size hard to judge. Position by careful star hop. Glow only
