Comet Hale-Bopp on April 4, 1997 had a relatively homogeneous dust tail and a multi-stranded
blue ion tail. 
Photographic Data: This single 20-minute exposure was made with an Astro-Physics 130 mm
(5-inch) f/6 refractor, 35 mm Nikon F2 camera and Kodak  Pro 400 PPF film, while guiding
on the comet's head.  The negative was scanned in the raw color mode.  This film/scanning combination shows the dust tail to have a white to pale yellow appearance.  Its semi-transparent
nature allows stars to shine through the less dense periphery.  The small nucleus is also seen to
better advantage.
