Other: Taken on the MAS Grounds, 1-3am in very cold January weather, 17.75 SQM reading, with a bright moon on the snow. The star reduction version removes all star trails except the bigger star blotches which can be seen whizzing by as the comet zips through the frame. This is my favorite instead of adding a starfield back in, as it helps you spot the comet characteristics, tail and the active tail amidst blur, which resembles a projectile. More at Astrobin
