Description:

Description:

The aim is to provide a network of well-determined star positions covering the Southern sky with a density of one star per square degree. They worked in association with other observatories in the Southern Hemisphere e.g. Australia, Chile and Argentine. The SRS was part of a bigger project, the southern extension of the Astronomische Gesellenschaft Katalog (AGK3R).

History:
The
CPC 50 project photographed the Southern sky between the -30 degrees and the -52 degrees. The SRS project aimed to photograph the rest of the southern sky. The idea was to take overlapping photographs with colour corrected cameras. “Positions measured with it should therefore be relatively free from the differential colour effects that bedevil astrometric measures made on plates taken with more conventional equipment.” [Copied from Laing, p.31.]
During this time they made great advances with computerised measuring machines, such as the GALAXY machines used at the Royal Observatory Edinburgh. (Effect on projects like this?)
