I took this near the antennas in Billings looking northwest at the thunderstorm last Thursday. I would have preferred it without the phone line in the upper corner. It is a stack of 32 images, each had the following settings: 30" f/6.3 ISO 100.

Taken on a Nikon D600 with a Sigma 24-70mm f/2.8 lens.
