Comet Halley. April 4, 1986.
5 minutes exposure.3M 1000 slide film. 50mm f/1.8 Yachica camera.
At the beginning of April, the comet was situated in a very bright region of the Milky Way in Scorpius. This made observations of the tail quite difficult. The faint, blue ion tail visible in these photographs, was almost impossible to observe visually.
Combination of the above two images.
