The photographer at work reviewing an asteroid recently detected with the Spacewatch Mosaic camera. This self portrait was made with the camera in timer mode on a tripod using the 70-300mm zoom at 70mm focal length on my 20D. The exposure was 1/20 seconds at f/11, ISO 3200. I added an incandescent light to spot my face and improve the lighting that otherwise was blue from the computer screen.
