A display of Northern Lights along with noctilucent clouds on the northern horizon at right being lit by the Sun. Perpetual twilight colors the sky blue and the horizon a deep orange. A remarkable display of cky colours. This is a single frame from a 120-frame time lapse, with the Canon 60Da and 10-22mm lens at 10mm, for 30 seconds at f/4 and ISO 400.
