Marko Moilanen and Arto Oksanen of the Nyrola Observatory, Finland, took this image of Tempel 1 on September 5 at 0.5 hours UT. This image is a composite of 12, 120-second exposures using a photometric red filter which emphasizes the dust in the comet's coma and tail. An SBIG ST-7E CCD camera was used with the observatory's 0.4-meter, Schmidt-Cassegrain telescope at f/6.3. The field of view is 10 x 7 arcminutes and covers an area of the sky that is one-tenth of the size of a full moon.
