I made this time lapse video of the PanSTARRS comet last night from just north of Hytop, Alabama. It gets noisy near the end due to the fixed exposure setting combined with a darkening sky. Taken with a Canon 5D Mk II, with a Canon 70-200 mm lens (200 mm at f2.8), ISO=250, 2.5 sec exposures taken every 4 seconds, HDR processing with Photomatix.
