Star Trails - Over the Boulder Flat Irons

Click Image for Larger Version

One of the main features I looked for when buying my camera was I wanted one that would allow me to keep the shutter open as long as I wanted so that I could do these star trails. And here's a result.

This was taken about a week after I bought my camera. It was taken from the CU Boulder SBO observing deck, and I made it black and white because I thought that made it more dramatic (it can be clicked on for a larger version). The levels were adjusted a little so that I could bring out some of the contrast, but the sky really is that bright. Boulder is no longer a dark sky location. The whisps seen are clouds that moved through the frame.
