Yes. The best I can do is my fast (F3.8) 10" mirror and hope for good seeing. I know its a long shot but what the heck? While that scope is grinding away, I can go to the other extreme and image with my FSQ85.

Summer nights up here are often not that great for seeing though. Even when weather cooperates, the upper atmosphere frequently boils like a kettle.
