This is a 15 minute exposure with a 135mm lens @ f/5.6 on Kodak E200 in a Mamiya back pushed to ISO 3200. The image was then scanned, converted to B&W and filtered to bring out the 8 degree ion tail, then sharpened once.
The ion tail of Comet SWAN (C/2006 M4) shows in this B&W rendering in spite of light from the first quarter moon.
