Beautiful comet Panstarrs sets over the Rockies. Note the fan-shaped tail with several streamers (the dust tail), and the straight tail on the right (the ion tail). This image was stretched very hard to show the faint outer parts of the tail.
Technical. Canon 1D Mark IV 16-megapixel digital camera, 300 mm f/2.8 L IS lens at f/2.8. Fifteen 2-second exposures from a fixed tripod were combined in two ways: 1) averaged images aligned on the comet, and 2) averaged with no following of the comet to show the mountains. The two averaged images were then combined. 30 seconds total exposure at ISO 1600. The mountains were lit by the 1st quarter Moon.
