Backyard Autumn Nigh Sky in New Jersey: Star, Jet, and Moon Trails.

View looking south. Composite of images taken between 17:30 and 23:58 with a Nikon D810a camera and 14-24 mm f/2.8 lens (ISO 200, 14 mm, f/5.6, 120 sec). I like that the Nikon D810a camera can take images for longer than 30 sec (up to 900 sec) just using the controls on the camera (external trigger/controller not needed). This results in smoother composite star trail images with fewer gaps.

Backyard Autumn Nature in New Jersey: Red Leaves, Moon, and Star Trails.

Bright red autumn colors with some bokeh at sunrise. Japanese Maple leaves before they drop. Tree was almost killed by wild grape and poison ivy vines a few years ago, but since they were removed the tree has recovered. Image taken with a Nikon DF camera and 300 mm f/4 lens (ISO 100, 300 mm, f/4, 1/400 sec).

This was one of the first shots with my repaired Nikon DF camera. The shutter buckled when I was in Antarctica with less than 100K images. Unfortunately, the camera was out of warranty so I didn’t send it in for repair for a long time.
