Running 4.5 Magnitude and still
easily visible in the western sky after sunset, the comet is
fading rapidly, but still bears a long blue ion tail and the
peculiar green fan off the coma. This image was taken with the
5.5 inch schmidt at our observatory in Payson, which is at an
elevation of 5150 feet and not near as dark as our Happy Jack
5.5 inch Schmidt camera mounted on the side of my 12.5 inch newtonian.
A 5x24mm finder acts as centering device for the field, which
is set up just before the night shooting by aiming at Jupiter
or Venus and centering the image in the film plane on a white
piece of paper the size of film. Then the finder is pointed at
the same object.
