There is about
one comet per 2 years that reaches naked eye brightness on the
average. This year, we will get a great view in the coming month
of what has been called the Christmas Comet of 2004. I am presenting
two images here, taken with the 10D on the robotic barn door
tracker of the comet as seen Friday night. The upper image was
taken at 28mm f/3.5 and the lower, 100mm f/5.6. Both exposures
are 10 minutes in duration. The comet is the only green object
in both pictures, the coma emitting the Swan bands strongly.
The 10D is turning out
to be absolutely ideal for comet photography. It has the exact
spectral response to capture the greens and blues, excellent
light sensitivity at ASA 800 and 1600, and very little noise.
