I've been looking forward to seeing photo's of this comet! When we were up at the ASWA Tammin site on the 27th-29th December we took a look at it and it was surprisingly big and bright through an 8" SCT and 15" Obsession.
I've thought of gettting a shot myself but haven't got around to it yet, if I can see it through the tress (not a good north for me at home).
Nice result you have here
