Northern Exposure

This was my first attempt at star trail astrophotography. It's pretty obvious which star is the north star in this photo!

EXIF Information: I used a tripod, a shutter release cable, my 18-70mm Sigma zoom lens (set to 18mm), f/5.0, ISO 100, and a 30 minute exposure. Tomorrow, if the weather cooperates, I may try a longer exposure with f/8 to get a little darker image. This one was pretty bright, mostly from the reflection of the dastardly sodium vapor light in my cul-de-sac.
