This was the night with a clear sky for a long time. I set up two cameras to record the nighttime sky for composite Star Trail images. The first a Nikon D810a camera with 19 mm f/4 PC-E lens looking west. I like this camera for nighttime sky photography because it can be set to take images longer than 30 seconds (up to 900 seconds). The second a Nikon D850 camera with a 8-15 mm fisheye lens looking up from my patio. I forgot to reset the ISO for the Nikon D850 camera from 100 to 800. When I looked at the images, they were all black — but since the raw for this camera have an amazing dynamic range, I was able to increase the brightness by 4 stops during post-processing and get decent images…
