COMET 41P/T-G-K AND THE BIG DIPPER Taken by Paul Nelson on March 22, 2017 @ Marquette, Michigan, USA

It was a beautiful, cool clear night. After photographing a brief Aurora display, I decided to try to capture an image of Comet 41P/T-G-K, which I knew was passing through the dipper in The Big Dipper. I used a Canon 6D and 70-200 f/2.8L on an iOptron SkyTracker Pro, 70mm,f/2.8, 96 sec, ISO 3200
