David's Images of the Day Photoblog
Second night in a row the sky was clear, so I set up two cameras to record the night sky (and hope to see some meteors).

The sky looked relatively clear again, so I put two cameras out to record the night sky. This time I remembered to set the ISO on the D850 camera correctly. I managed to see a couple of small meteor trails (Taurids?).

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…

This was the second night in a row that we had clear skies, so I set up a Nikon D810a camera with a 8-15 mm fisheye lens (ISO 200, 9 mm, f/8, 120 sec) to record the night sky. I still have an issue with condensation on the big lens. I may need to rig up a tape heater for the lens. The other thing I am seeing with a very wide-angle (9 mm) lens, and a relatively high-resolution sensor (35 megapixel) is the size of the star images is very small. I think I got better star trail images when I was using 12-16 megapixel sensors). The next clear night, I plan to set up a side-by-side comparison.
