Possibly the most photogenic part of Comet Panstarrs apparition occurred on March 12, 2013 and luckily, I had clear weather. I took a number of images, all with a Canon 200mm at F/2.8, a Canon XS (modified) and my little CG3 mount and a laptop. This particular image is a 2 second exposure at ISO 800.
I shot this at the start of the session, before the comet and the moon sank too deep into the murk. This is a one second exposure at ISO 200, Canon 200mm lens at F/2.8. Lots of twilight still, but dark enough to show a good portion of the comet’s tail.
