Autumn Backyard Night Sky Over New Jersey.
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.
