Maybe it's my imagination, but I can barely make out the comet's tail trailing to the upper-left. The stars are streaked due to the Earth's rotation. This was compiled from 5 8-second exposures at ISO-3200 using a Canon EOS Rebel T3 (1100D) with a zoom lens at 55mm.
This is a wide-angle image that shows the comet's location on the night of December 30th. Click on the labels for the indicated objects to open pages that give details. Some of the links will open pages on other web sites.
