The image is a composite of 6 images taken at three exposure times (15 sec, 30 sec, 60 sec) with a Canon 20D dslr, ISO 800, manual settings, which was mounted at prime focus to a Celestron 105mm "spotter scope" attached to a EQ-5 equatorial drive. The images were combined using Registar v1.07 and finished with Photoshop adjusting the red channel to remove excessive light pollution.
The image shows Comet 17P/Holmes passing Alpha Perseus on the evening of November 17, 2007 at 8:40 pm. The nucleus of the comet is clearly visible as is the extended tail. It also shows apparent motion as the leading edge of the scattered light is rounded but the trailing edge is not.
