Backyard Winter Night Sky in New Jersey: Star and Jet Trails.

I used a 16 mm Fisheye lens to take acquire some winter night sky images. The images were combined using the startrails.exe program to get the star trail images. The first image is a composite of 15 60 second images relatively early in the evening. The next three are composites of 16, 35, and 300 second (5 minute) images.
