Stacked image to get longer exposure

This image was created by stacking nine 60-second exposures that were made over the course of a 30-minute period.  The comet is moving through the sky quickly enough that aligning the comet in all the images causes the star images to spread out in a line.  With this view, we can see just a hint of a tail extending toward the bottom right, but it's pretty faint.  These exposures were taken during the early morning hours of October 12, 2010, using the Center for Astrophysics MicroObservatory remote-controlled telescope in Amado, Arizona.
