Comet Catalina (C/2013 US10)

This was my first attempt to get an image of the comet C/2013 US10 (Catalina).  The images are from my work parking lot (Seymour High School) in southern Connecticut.  I don't consider these images to be that good, as I was hoping for better.  However, when I first looked at them I did not think I got anything, Southern CT isn't known for dark sky's and this comet isn't living up to early expectations.  It was only when I playing around with Photoshop and Picasa3 that I was able to resolve the comet.  I plan on getting respectable images with my telescope when it passes within 1 degree of Arcturus on January 1st or January 16 when it is close to the handle of the Big Dipper.

The comet became visible to viewers in the Northern Hemisphere in mid-November and is now heading away from the sun on its way back to the Oort Cloud from which its hence.  According to Kelly Beatty (Sky and Telescope) it will be closest to Earth on January 12 at a distance of 0.72 astronomical units (108 million km).
