Observer: Bob Yen
Location: Mojave Desert, California
Date: March 19, 1997

First image is a long telephoto shot, using a 6x7 camera on an AstroPhysics 610mm f6 lens w/field-flattener (Traveler). The ion tail is very strong , and extends out of the frame (in spite of moonlight) -- at least 6 deg. The dust tail has become more intense (brighter and narrower), but still has an outer *fan*.

Second image is a telephoto shot, using a 6x7 camera & 75mm/4.5 lens stopped down to f4 (the same field of an 50mm lens, 35mm format). You can see the Northern Milky Way, towards Andromeda. Wow. A memorable moment.
