Summer Nighttime Sky Over Colorado.

Star trails from my room at the Marriott Residence Inn in Boulder, Colorado. Composite of 180 images taken with a Nikon D3 camera and 24 mm f/3.5 PC-E lens (ISO 200, 24 mm, f/5.6, 30 sec exposures). Raw images processed with Capture One Pro 8, and combined using Photoshop CC 2014 (scripts, statistics, maximum). Note that these images were taken using the in-camera intervalometer and noise reduction so for every minute, only 30 seconds of exposure. I’ve learned how to do it better since then — using an external intervalometer and doing the noise reduction post processing.
