Lightning over Tucson

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.

 This image is looking over Oro Valley, in the general direction of Biosphere 2.  Twilight was still heavy when I took this exposure.  The exposure is 2 second at f/4, ISO 1600 with my 70-200mm f/2.8L lens at 70mm focal length.

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.
