The pictures on this page were produced using a film camera attached to my telescope at prime focus,
through an f/6.3 focal reducer. Both pictures had the same exposure time. Both pictures were
scanned from a printed photograph. These pictures illustrate the variations in colour sensitivity of different
types of film at low light levels.
2 minute exposure, f/6.3, with Fuji 800ASA film, November 2002.
2 minute exposure, f/6.3, with Konica 400ASA film, January 2003.
