Tried my first startrail last night in Pennsylvania. It turned more into a learning experience than anything else.
Biggest mistake of the night, do not discount the moon. No matter how small it is. The moon was about 90 degrees to the photos left side. It provided enough light to make it look like daylight when the shutter was held open for 30 minutes. Startrails are visible but I need to try again when the moon is not in the sky.
f4 iso 200 @ 17mm for 30 minutes.
While out I saw 3 satellites and 2 shooting stars in about 15 minutes.
