Nice result Tony. This dim sucker is on my to do list over the Summer season. I've had a few goes at it but never got anything as good as yours. I even tried it last night, though it was not a serious attempt, just an experiment to see if it was gettable from the location I was at. I have a filter similar to the one you're using, so I might try it out on the Witch and see what difference it makes. I like the colours you've managed with this shot too. Good stuff!
