Description: Danjon prismatic astrolabe (4 inch).This instrument came to the Cape Observatory on loan from the Royal Greenwich Observatory at Herstmonceux. It was installed in 1964. The purpose was for a special program to check the systematic accuracy of the fundamental system of star positions between -4 and -64 degrees. The program operated between 1965 and 1969. Approximately 1000 stars were selected from the SRS project. A byproduct of this work was to determine the latitude and longitude from each night’s observations and to report the results to the International Polar Motion Service and the Bureau International de l’Heure. |
