During a recent photo tour the skies opened up to a magnificent and lengthy display of the aurora borealis. The group I was co-guiding with Hugh Rose started clicking frames about 9:00 p.m. and finally went to bed about 5:00 a.m. It was a great night of fun and fanciful color and light in the night sky. Here are 35 favorites from that and the following night (Oct 12-13). The photos were taken with the Canon 5D Mark III at 1250-1600 ISO, which was amazingly clean and noise-free. I was surprised how well they looked, and how they handled post-processing adjustments and still held up to high reproduction standards.
