I watched a nice Lightning storm over the Tucson area tonight after sunset. Lightning appeared over Oro Valley and Mount Lemmon while it was mostly clear overhead on Kitt Peak.
Looking over Tucson with the Tucson Mountains in the foreground and the Catalina mountains behind them. A few strokes of lightning hit near the summit of Mount Lemmon with lots of other activity overhead. This image was a 30 second exposure at f/8, ISO 800 with my 70-200mm f/2.8L lens at 100mm focal length.
