Running 3rd Magnitude or better,
this superb object allows a good 45 minutes to get a crisp image
after twilight ends. These are all skyfog limited 4 minute exposures,
on a dark moonless evening at nearly 7000 feet with mag 7.5 stars
seen easily at the zenith. The two orientations seen here are
by rotating the film holder in the schmidt 90 degrees between
frames. Visually, the comet had a 2 degree tail to the naked
eye, however in binoculars, over 7 degrees of tail was seen without
much effort. THREE tails are seen here, one greenish tail pointing
upward in the top image, a blue ion tail and a brownish dust
tail. The green tail points away from the sun.
