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.
