We were lucky to have pretty clear skies as the Aurora Borealis, rarely seen this far south, danced for us once again.
This time I set the camera to shoot one frame every ten seconds. With a six second exposure time at f/5 using ISO 1600 on the Canon 5D mark II, the speed is almost right, and the quality of each frame is surprisingly good. My Canon EOS 1Ds Mark III does not produce quality like this at that ISO.
I had to get up 2 times during the night to change batteries. The larger part of the images had very calm or very little action, so this is the best 1000 images of about 3000 that the camera shot during the night.
Still, the most violent movements of the Aurora are barely captured with this 10 second interval. I most go down even further to get better movement.
