My son & I hiked into Delicate Arch about 10:00 pm. We wanted to shoot star trails with the North star showing thru the arch. Can't do that as it is too steep of a drop off on the south end. So we shot the traditional view. I used a 14-24 2.8 @ 14. My son used a 16mm fisheye. We both use D-700's. The glow in the middle of the arch on the horizon is Moab. Orions belt is seen in the background. The moon was about 1/4 and behind us... almost perfect as it allowed the stars to pop. The temp was cold... about 27 degrees F. The exposure was 30 sec. @ 2.8. Your tripod is a necessity for both the shot and helpful against mt. lions. We did see one peering at us his eyes glowing in the dark... At least I think is was a mt. lion, my son thinks it was a coyote. Our version of extreme photography.
