The dark sky on the North Rim of the Grand Canyon. This image was taken on July 24 this year at our campsite in the National Forest just off of the North Rim, near the road out to Fire Point. The late afternoon rains let up and the sky partly cleared, but still mar this image. The silhouette of trees around our campsite against the dark black, starlit sky of the summer Milky Way near Cygness is apparent. This exposure is with my 24mm lens at f/1.8 for 15 seconds, ISO 3200.
