Finally a good capture of Comet C/2013 US10 Catalina! This was taken this morning at around 5:30AM EST through the main optics of the KPO Reflector. The comet did move along pretty well through the imaging session, so I had to do two stacks of the subframes, where one was aligned on the comet and one was aligned on the stars. I removed the comet from the star-aligned stack, and then layered them in PhotoShop.
It is easy to see the two positionally-opposed tails of the comet in this image. Click on the image for a larger version.
