I was out Sunday night trying to shoot the Milky Way in my light polluted southern sky. I shot 58 images and will filter them out later this week but as the dew was just beginning and I felt it time to pack it in I looked over my shoulder and saw this. It was too early in the night to shoot the entire constellation Ursa Major so I just got the asterism the Big Dipper. This tuned out not to bad considering it was an unplanned project. I didn’t even have time to take test shots, just got lucky with an ISO 1600, 6 seconds, f/4 on the Rokinon 16 mm lens and the modified Canon T7i. Shot at 8:17 pm 9/30/18.
