Période

1969- to ca 1980

Canada

Used for the first Canadian attempt at double station photographic tracking & triangulation of meteors, producing a wealth of knowledge recognized all over the world. Two of six cameras made were bought by the Canadian government for the Dominion Observatory. The programme was called MORP (Meteorite Observation and Recording Program). Twelve meteor tracking stations were established across the Prairie provinces in 1969, in a network stretching from Alonsa, Manitoba in the East to Lousana, Alberta in the West. They were situated sufficiently close together for a meteor to be recorded at two or more sites. The recorded tracks would then permit calculation of both the orbit in space and also the likely area of fall. The situation in the central and southern parts of the Prairies where farmland is dominant, maximised the chances of recovering samples of any meteorites believed to have fallen. (Camera Stations had previously been established in Czechoslovakia and the U.S.A.). (Courtesy National Research Council of Canada; Ref. Halliday et al. (1978): J. Royal Astronom. Soc. Canada, v. 72 p. 15-39)

Fonction

To photograph large areas of the sky with a camera that can be triggered at a preset frequency.

Technique

Combines wide field in good focus with a very fast effective aperture ratio by using two hemispherical shells of thick glass on either side of the compound correcting plate; maximum possible exposure without shutter and a moonless sky is 3-4 minutes.
