Comet Schwassmann-Wachmann 3. May 24, 1990.
16 minutes exposure, Fuji 400 film.
5" f/5 refractor at prime focus.
The 1990 return was moderately favourable, with the comet peaking at around 9.5 magnitude.
This photograph is one of the earliest that I have of the comet, and shows the typical appearance prior to 1995.
