Silver River Shimmers, 2017
Photograph notes: This is a composite of 4 vertical frames stitched for the sky and another 4 vertical frames stitched for the land for a total of 93.8 million pixels, using a Sony a7R II at ISO 800 and Canon EF 35mm f/1.4L II USM. Each of the sky frames was stacked and averaged from nine 32-second exposures at f/2.8. The land frames were stacked and averaged from four 32-second exposures at f/4 made 23 mins later at predawn to avoid shadows from the sun. 52 exposures were used in all. The sky exposures were tracked with a Sky-Watcher Star Adventurer.
