|The Milky Way intercepts Long's Peak. Immediately after this photo, clouds moved in and it began to rain. But, it was a glorious scene up to that point. The Y camp shines in the valley on the lower left. Canon EOS 5D Mark IV, Rokinon 14mm f/2.8 ED AS IF UMC. 25s@f/2.8, ISO 2000, lens focal length 14mm., 05/25/17 1:38am.
This shot was made possible by the new moon and the cloud cover over the front range megalopolis (Denver, Boulder, etc.). The light pollution was blocked, as I shot to the southeast from RMNP's "Many Parks Curve". Most importantly, astronomical dawn was about an hour away. Astronomical dawn is the time when the geometric center of the Sun is at 18 degrees below the horizon. Before this time, the sky is absolutely dark.
Technical note: Manual settings using the "rule of 500" as a guide. 500/14mm = 35 seconds. Knowing that 35 seconds would have still allowed stars to appear as points of light, I set the exposure to 25 seconds to be safe. I would have raised the ISO speed somewhat, if it hadn't been for the city lights on the clouds over Denver. The dynamic range of the scene was wide. My camera handles the electronic noise very well.
