For the second night in a row the sky was clear so again I set up two cameras. This time using lessons learned from yesterday. One for firefly trails (Nikon D810a camera and 200 mm f/2 lens), and one for star trails looking north (Nikon D850 camera and 19 mm f/4 PC-E lens). This time the focus point for the firefly trails was moved back, and the orientation changed to portrait. I like this better than last night. For the star trails image I rotated the camera to north to get the circle around the north star. The star trail images really needs to be viewed on a large high-resolution monitor. 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 Big Dipper pointing to the north star was one of the first things I learned about the night sky. One note post processing is with these high-resolution cameras it took me all day to do the processing, even with my fastest computer with a video processor (Microsoft Surface Book II Pro).
