Table information for ''


This table is available for ADQL queries and through the TAP endpoint.

Resource Description: The Armagh-Dunsink-Harvard Becker-Schmidt Telescope was deployed at Boyden Station, Maselspoort South Africa between 1965 and 1970. During that time, astronomers from Bamberg, Heidelberg, Hamburg and Münster took astronomical images there, with a focus on old star clusters, the Magellanic clouds, and the southern milky way. This service provides scans of the plates obtained.
