Description

Taken at Mather Point, Grand Canyon National Park (South Rim). The streaks near and through M42 are from geosynchronous satellites. The lens was stopped down to f/4. Tracking was done internally in the camera using its Astrotracer feature, with the camera mounted directly on a tripod. 

If you are wondering why such a pitifully short total exposure (only 1.5 minutes), wind gusts at the edge of the canyon were so strong that most of my sub-frames were ruined by vibration of the light travel tripod I was using. A hard lesson but live and learn.
