Comet Lovejoy 20min
Single 1200s (20min) exposure at ISO400 through SW Skyliner 200 on NEQ6 mount, PHD guided. Photoshop CS3 processed. The true movement of the comet nucleus with respect to the background stars over the 20 minute exposure time causes it to appear as a short bright line rather than a distinct point.
