First Light


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.

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



This image was the first actually semi-focused image taken with the camera. It is of a ceiling beam in the RAS office. The lens used was a 25mm eyepiece. A blue filter was also used. Image by D. Armstrong



I mated a 28mm camera lens on the CCD head and took a few portraits. The lens was stopped down to f/8 and a yellow filter was used. Image by D. Armstrong



This is another stellar shot in Cygnus. Image by D. Armstrong
