My last attempt at this last week taught me a few things.

I reshot it last night and reduced the subexposures times in the luminance from 5 minutes
before to 2.5 minutes in this one.

Very nice picture. This is certainly a very concentrated globular!

You should provide a warning with that shot, Greg: please put on your sunglasses before opening 8) Absolutely amazing. Great resolution right down to the core. Sure would love to capture a glob that well some day.
