Beware the....CRAW!

I was intrigued by the dark clouds in this area after seeing some more of John's amazing mosaic exploits in Sagittarius, so I took the opportunity to explore this area for a few hours when visiting a dark sky site recently. The dust clouds haven't contrasted as well as I'd hoped against overwhelming star field, but its a bit out of the ordinary, so hope people find some interest. I don't think I'll get time to play with the processing for a while, so putting it up as is.

The CRAW (not the Claw you idiot!) is really B84, and the glob is NGC 6440. Planetary neb NGC 6445 is the purple smudge near the blue star far left.
