Comet ISON time lapse, morning of Nov. 18, 2013, near New Market, Alabama. I was hoping the clouds would clear in time to reveal the comet, which is just what happened. This first video is from ~300 20-sec exposures. 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 filtering through the clouds combined with the sensitive camera and lens...by eye, it was much darker.
