Timelapse of Aurora Borealis "Northern Lights". Assembled of single images taken on 8. October 2011 in Porjus/Schweden near the polar circle.
Cameras: Canon EOS 40D with 8mm Samyang Fisheye, Canon EOS 7D with 12-24mm and 24-75 Sigma lenses.
Shutter time 15s - 1 s, ISO 800 - 12800.
Especially the Corona was so fast that I reduced the shutter time very much to show the dynamics of the Aurora.
