Backyard Autumn Nighttime Sky Over New Jersey.

Earlier in the evening it didn’t look promising for a clear sky. I checked again after midnight, and did see Orion and some other stars. I set up two cameras same as the previous clear nights to take images for star trails, and if lucky catch a launch of a rocket from Virginia at 04:01. Unfortunately, I only got 15 minutes of clear skies before the clouds rolled back in. I did check again at 04:00 for 5 minutes, but it was still overcast and I didn’t see the launch.

Backyard Autumn Nighttime Sky Over New Jersey.

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).

Backyard Nighttime Sky Over New Jersey.

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?).

Autumn Night Sky Over New Jersey.

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…
