M13 wide field

An almost full moon smack dab in Leo made me abandon the Trio early, so I swung around to a very low lying M13 on the opposite side of the sky. Thus the very wide field for this object. But I did catch very, very faintly the galaxy NGC6207 to the left of the cluster; always fun to have those bonus objects! LRGB of 30/10/10/14--maybe the reason for the very bright blues.

Any suggestions always appreciated (make that needed!)

The image is too dark to see the faint stuff. It looks like the histogram is clipped.
