These aurora were very impressive here in NE Wisconsin starting subtly and eventually getting more intense as the night progressed. I even captured the ISS in one of my shots.
Cameras used were a Canon 60D and 40D with various ISO settings. The lenses were a Zenitar 16mm and a Peleng 8mm fisheye.
A timelapse is in the works and should be up on my webpage on the 13th at some point.
