84



The brightness of the stars and the sky that should be black are indicators of how bright or faint the aurora was at any given time. All of the photos I am posting were taking in less than three hours, and in that time the dynamics of the aurora changes quite a bit. I think with the brightest aurora I was able to get down to a one second exposure, in which the sky is very black. Most of the photos had exposures between 3 and 8 seconds.

Exposure time: 4s
Aperture: f/1.8
ISO: 1000
