Galactic Rainbow

This shot was taken a couple weeks ago on an incredibly clear and calm night on the coast of Maine. The airglow was very active that night, which is the green coloration visible in the sky. Airglow is the result of various chemical reactions in the upper atmosphere that emit light, and on some nights it’s much more active than others in certain areas. It’s very difficult to see airglow with the naked eye, but the camera has no problem capturing the dim light in a long exposure.

This is a panorama made up of 10 vertical images. Nikon D810A and Nikon 14-24mm f/2.8 lens @ 14mm and f/2.8, ISO 10,000, 20 seconds per shot.
