I do indeed...see attached. Obviously, a bit more challenging than a reasonably bright glob, but still not too bad for 10 minutes. FWIW, my dark subtraction didn't work so well on this one
I should add that my newt dewed up at some point and I don't exactly know when. M19 was my first target and was quite low in the sky at the time, whereas NGC6357 was later and higher.
