Thanks everyone. I knew I only had about five minutes between rising above the local trees and start of astronomical twilight from experience the night before, so threw a few minutes guided exposure and binning at it.
At least I can say I "saw" it.
Rick, I couldn't stay up that late again on the 3rd (Fri) night and hit the sack before 3am leaving it all tracking on the Rosette.

Hope you're all still having fun - looks like another stunner tonight!
