Comet ISON-131118-Canon250mm-12X10sec1600isoc

The sky was already beginning to brighten by the time the comet rose above horizon hugging clouds so I could grab this shot on the morning of November 18. It is a stack of 12 10 second exposures at ISO 1600 taken with a Canon 450D and a 55-250mm zoom lens mounted on a Celestron CG-5 Equatorial mount. Images were stacked and processed in Images Plus.
