Summer Nighttime Sky Over New Jersey.

Composite of nearly full moon images. Rather than an in-camera composite image (as I have done in the past), these were created during post processing (Photoshop CC Pro, statistics, maximum). I set a Nikon D5 camera up with a 600 mm f/4 VR telephoto lens to take images every 1 second. I was hoping to catch a jet pass in front of the moon, as I had seen the previous night — but no joy. When I get some time I will make a time-lapse video of the moon crossing the screen.

Backyard Summer Nighttime Sky Over New Jersey.

For the first time since I returned from Germany, the sky was predicted to be clear overnight.  I have been wanting to try the 8-15 mm fisheye lens (that I borrowed from my brother) for doing some star trail images, and night sky time-lapse videos. I did have an issue with condensation on the very wide lens in the early morning hours. I have had the condensation problem on other wide lenses (14 mm, 14-24 mm) in the past, and may need to fashion a small tape heater on the lens.

Raw images processed with Capture One Pro, and the composite generated using Photoshop CC (statistics, maximum). Individual images from the slide show can be viewed here.
