1980 Jan 22.5  - C/1979l (Bradfield) at magnitude 6 in Octans.  Unguided photo, 50mm lens. A short tail points toward 10 o'clock. This view of the southern circumploar sky was taken from my roof top in Adelaide in the early evening.
 

1986 Feb ?? -  Comet Halley was in the pre-dawn sky and had a nice naked eye tail around 3 degrees long. The predicted peak brightness was not until April, but by then it had faded significantly. This was a test exposure but with 20/20 hindsight it proved to capture the comet at its brightest. Tri-X film, 135mm lens.
