Lightning storm near Kitt Peak

Last night while waiting to observe on the 4-Meter Mayall telescope on Kitt Peak, a lightning storm passed to the southwest of Kitt Peak.  Here is some lightning to the southwest of the mountain with the Steward Observatory 90 inch Bok telescope building lit by the Moon in the foreground.  The image was taken with my Canon 6D with my 50mm lens at f/8, ISO 1600 with a 20 second exposure.
