No planetary. For 20 minutes or so, we strongly suspected that indeed what we were seeing could very well be the comet. I decided to set up the CCD and see if I could detect motion among the background stars. It didn't move. No comet. But this thing was big and easily seen... why was it not in any of our charts. I finally pulled out the "big gun", the Millenium Star Atlas. Sure enough, there it was. So, we didn't find a comet. But the chase was pretty fun. And I got an intersting CCD shot out of it. You can actually see a wagon wheel structure spreading outward from the central star.
This exposure is composed of 10 one minute shots in binned mode at F10. SXH516, C11.
