Star Trails of Constellations

These are photos from the Canon T4i camera on a fixed tripod, taken at Charlie Elliot field on Sep. 3, 2013. I photographed 4 different constellations, making a series of 30 sec. exposures for 10-15 minutes per constellation. Using Voyager4.5, I was able to identify individual stars and find their Temperatures. The goal is to see if the star temperatures correspond to the observed star colors.
