Backyard Nighttime Sky Over New Jersey.

The sky was clear so I set up two cameras. One for firefly trails (Nikon D810a and 200 mm f/2 lens), and one for star trails looking south (Nikon D850 and 19 mm f/4 PC-E lens). The focus point for the firefly image should have been further back. This is my first star trails image with the high-resolution Nikon D850 camera (8256 x 5505 pixel — 45 MP sensor). The image really needs to be viewed on a large high-resolution monitor. I focused the camera using live view using a magnified bright star. I need to figure out how to do the same thing with the firefly images. I also made a time-lapse video (five hours compressed to 20 seconds) of the night sky. This is best viewed on a high-resolution monitor in a dark room. The brightest object that shows up in the early morning is Mars.
