Great set of observations, Michael! That sharp edge you saw has been noted by a
few other observers on the list as well, in particular Todd Gross in his 16"
scope:

And meanwhile, William Schart agrees with your impression of knotted "arms" in
the stellar outliers of this fine globular:

Keep these careful and well-logged observations coming, please! (Also, please
use the form "M13 (NGC 6205)" for your object IDs: believe it or not, the "="
equals sign is actually used in some catalog IDs! :>)
Clear skies, and take care!
