The next comet to watch … ISON
WHEN Comet ISON was discovered by amateur astronomers in September last year it was quickly dubbed the comet of the century.
Dr Roy Spencer is watching it, producing a time-lapse video, here: Comet ISON time lapse, Nov. 11, 2013
November 11th, 2013
This is my third attempt at a time lapse video of Comet ISON from this morning, Nov. 11, 2013, near New Market, Alabama.
I used a Canon 6D with Canon 200mm f/2.8 lens with Canon 2x extender, at f/16, ISO 1600, 77 60-sec exposures. Tracking with Astrotrac on a Ravelli tripod. Temperature was about 43 deg F.
