Amazing! Is this one of those shots where you have to cut the comet out of its background because the stars are moving in each shot? And then you pick one background field for the composite photo? Is Richard on this list? I also live in Sandy and would love to watch the master work or get a tutorial on how to capture data like this and then process it. I wonder if he'd be willing to let me sit and watch one of these mornings.

Sure puts my anemic efforts at working the comet to shame. And the picture taken in the city (Sandy) no less.
