Right under the Dumbbell Nebula is is M71, a tight open cluster that looks like an arrowhead.   It has the tightly packed appearance of a globular, but it is not.  This is 10 minutes worth of exposure in 8 sec sub-images.

The image below is a shot with about 16 minutes of exposure (119 x 8 sec.)  I caught a few more background stars, I think.
