Fisheye view of spring constellations


Today, May 21, 2011, I went out to Sokum Ridge Park (the observing site of the Iowa Astronomy Club) and took some images. The sky was pretty dark and clear at about 9:30PM. However, in some distance (maybe above Muscatine, IA) there were lightnings from thunderstorms. At about 11:00PM the clouds and storm arrived at the park and I took off. This image is a stack of 4 images (ISO 400, 30s exposure time) using the Canon 300D and a 19mm/f3.8 Vivitar lens to which a fisheye lens was attached. The light at the horizon is from the lightning that took place presumably over Muscatine, IA.
