I took a few 5 minute exposure last night of the Comet and to my surprise there was an interloper in the photo. Starry Night didn't show any other object in the field, so I sent the image over to Terry Lovejoy to see if he could enlighten me. (thanks for the quick response Terry)
It turns out it was Asteroid 437 Rhodia. Oh well. But still it's nice to have the two in the same field of view.
