In the Northeast 25 miles from New York City, the night sky is too bright for photographing stars formations in the night. But it is still fun to try and see what you can get. This is shot at 20 secs, 16mm @ f/4.5 @ 3200 ISO. The plane flying through left an interesting arc.
This one is about the same exposure but moved a little to the right, a little more towards the direction of NYC, so the right side is a little brighter. The next one is shot a little higher and you can see it is even brighter on the right side. Again a plane was starting to fly through during the 20 second exposure. I think I would have had better luck shooting more to the left, but had too many tall trees in the way. In this area it is hard not to get a plane flying through, but it is still fun to try different techniques and fine tune them.
