<P>This image was a 2 second exposure taken with a 10" f/6 Newtonian. The star is Albeireo, Beta Cygni, a optical double. With a two second exposure the electrons trapped in a pixel spill out along rows creating the long vertical spike. The 4 diagonal spikes are from the secondary mirror supports. This image was taken on December 27th at 6:40PM.
<P>Beta Cygni was the first photo taken through the Schmidt camera built 1938/39 by Thorton Page. The image was taken on October 11th, 1939 at 8:30PM. The Newtonian is the current telescope occupying the tube used. Image by D. Armstrong
