The create this photo I shot 875 frames over a period of five hours and ten minutes on the south shore of the Salton Sea. Each shot was done at 20 sec f/3.2 ISO 3200 with my Canon 6D and Sigma 15mm lens. I spent over eleven hours removing airplane trails.
The weather was perfect: clear skies and the water was dead calm almost the entire time. Finally, I stacked the shots in StarStaX to produce the result you see here.
