Great report Ted. I happened to view a couple of those globs at the same time as you from an orange zone.

NGC 6520 was a real treat. The brightest inner portion was nearly a perfect circle with 20-30 stars resolved and there were a few bright stars outside the circle. Was this the impression you got? I noticed you didn't mention the glob NGC 6540 in your report; it shares the field with 6520 at low enough power as they're only about a degree apart, and it's a very interesting pair. 6540 was very faint but looked to me like it was pinched in the center with an eastern (larger) and western (smaller) portion. But I missed B86 so that will be something to look for during my next dark sky session. I tend to skip over the nebulae (bright and dark) that are just little squares in my charts.

NGC 6522 and 6528 also fit in the field together if you have an eyepiece that provides about a degree of FOV. I imagine that's nearly impossible with a 25" scope though. 6522 appeared a tiny bit brighter to me than 6528 but they were both unresolved fuzzballs in my scope.
