This photo of Comet Holmes was taken a couple of weeks after its outburst, from Rick Scott's back yard in the suburbs of Phoenix, Arizona, with my camera on Rick's home-made 9.8" Lurie-Houghton telescope. Three identical exposures were combined digitally for noise reduction. The comet's expanding shell of gas and dust formed a round, delicate glow that many people likened to a jellyfish.
Thanks to Rick for scanning and processing of this image. To see Rick's much-better photo taken the same night, click here.
