Wheeling 'round the Round Building

Stars wheel over a round farm structure located on Alburnett Road at 29th Avenue in Marion, Iowa from 8:00-8:15 PM, Saturday, January 28, 2012. This image looks south from the edge of the grounds at Christ Community United Methodist Church. The star trails were created shooting a stack of 30 30-second exposures at f/5.6, 250 ISO, 40mm focal length and converted to a single image using StarStaX software. I used a flashlight to "light paint" the round structure on the first exposure. The brighter streaks at upper left belong the lower part of the constellation Orion. Clouds began moving into this field of view around 8:15, preventing a longer set of exposures. Air temperature was 31 degrees F.
