Comet Holmes looks huge! I can't believe that I can still see it 2 1/2 months later. And what an incredible experience to see two naked eye comets at the same time. Tuttle's color appeared a nice teal green...very cool stuff!
Images taken with Canon EOS Rebel and f/5 refractor at ISO 1600 90 seconds for each part of the composite, so the comets are to scale. The wide field image was taken 3 days earlier on December 29th at ISO 1600 for 60 seconds.
