Backyard Nighttime Summer Sky Over New Jersey.

Another clear night and I set up three cameras. Two to record firefly trails, and the other to record the nighttime sky for star trails. I still need to do some testing, but it seems that the Nikon sensors do a better job with low light images (less sensor noise). And among the Nikon sensors, the D810a camera does better with exposures over 30 seconds. In addition to the star trails, I also did a time-lapse video of the night sky.

Backyard Nighttime Sky Over New Jersey.

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).

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.

Backyard Nighttime Summer Nature in New Jersey.

Fireflies in my backyard. Composite of 110 images taken with a Nikon D3s camera and 600 mm f/4 VR lens. I liked this image, and have used the camera and lens parameters to help get better subsequent images.
