July 25th

The comets tail is now becoming fan shaped and much shorter. this image, taken with the 8" f/1.5 schmidt camera from Payson is a composite of two 2 minute exposures with the comet registered. this makes the stars double, since the comet moved noticeably between shots. The yellowish color is due to the comet being composed of primarily dust, with little or no Ion tail seen in this image. Kodak PJ400 film.

July 19th

Blazing across the sky at 6 degrees per day, photographing the comet is getting to be a real tracking challenge. For this shot, two 2 minute exposures with an 8 inch f/1.5 schmidt camera on Kodak PJ400 from my backyard in Payson Arizona were taken, and scanned then digitally combined to create a single 4 minute equivelent exposurre. Since the comet moved about an arc minute between frames, the comet had to be registered at the expense of doubling the stars. This makes the comet appear stationary, while the stars whiz by. This image is cropped from the center half of the negative.
