I was very excited to finally photograph a Sprite on the American Plains! There was bright green atmospheric Airglow in the background with the M31 Andromeda Galaxy rising above the horizon. Despite seeing Sprites before, I still was lucky to record it because I had the camera set too low! I wonder how many earlier images Ive missed over the years with too shallow an angle? Sprites are really high up! You can see that the Canon 7D mII at 16000 ISO can capture it easily using a f1.4 lens, and some luck, time exposed for the prevailing conditions.

Atmospheric Electricity is pretty interesting. If you are in Birmingham, UK, come listen to Wal Thornhill talk about electricity on 14 July.
