Hi Terry,
love that shot especially that you have picked up that I.F. Nebulosity which I have cruised around in with our 20 inch Dobo a few times. I know that area around I.C. 4633 as being one of the brighter areas in that nebula. I'm surprised to see that spine still so strong in your image. That was the one thing in running around photographing your comet that I now regret not doing, and that was spending some time observing it at magnification!
I put together an album in FaceBook of my best shots from the past three weeks for all to enjoy.
