in the morning sky

A very photogenic approach of the 10th magnitude comet over the magnificent open cluster M35 in Gemini. This is a combined 1 hour exposure of the event, 50 mins of L frames, 10 mins of RGB data using the ST10xme CCD and Astrodon filters. The comet shows some beautiful cyan coloration from carbon ions in the head, and a golden dust tail extending to the right. North is up here in this 3 degree field.
