Comet ISON & Moonlit Clouds, I & II (time lapse)

November 18th, 2013 by Roy W. Spencer, Ph. D.

I took these this morning (Nov. 18, 2013), again near New Market, Alabama. I was hoping the clouds would clear in time to reveal the comet, which is just what happened. The first video is from ~300 20-sec exposures, the 2nd video used ~150 5-sec exposures (shot just after the first). I used a Canon 6D with 85mm f/1.2 lens and an AstroTrac for tracking of the stars. All of the lighting of the landscape was provided by the moon and the very sensitive camera and lens…by eye, it was much darker.
