This pleasing photograph of the November 8, 2003 eclipse has excellent resolution and great color. It also demonstrates the movement of the Moon across the sky. The entire sequence (from the lower right to upper left) was accomplished by taking multiple exposures, on a single frame of film.

By allowing the telescope to track at sidereal rate, the apparent movement of the sky due to the Earth’s rotation was effectively cancelled out. During the 5 1⁄2 hours needed to take this photograph, the Moon moved eastward, through the shadow of the Earth. Each image of the Moon was timed about 50 minutes apart. Thus, we have graphic proof that each hour the Moon moves its own width across the sky.

Equipment: Takahashi Sky 90 telescope, Nikon FM camera body, Fujichrome 100 film.
