Comet Lulin
Comet Lulin, imaged at around 4:00 AM MST on 21 Feb 2009. I think I see a faint tail to the left of the core.
Stack of 40 frames @ 30 seconds each, ISO 1600, taken with a Canon XTi through an Orion 80mm f/6 apo refractor. Somehow DeepSkyStacker can stack the image twice--once aligned on the stars, and once on the comet--and magically composite the two so the comet and stars are both sharp--very cool.
See a video made with individual frames here, showing the motion of the comet.
