This 26-inch refracting telescope began operation in Johannesburg, South Africa in 1925, as Yale University's Southern Station. Columbia University joined the telescope's research program in 1943, but increased light pollution forced the American universities to look for an alternate location and the telescope moved to Mt Stromlo and recommenced operation in 1955/6. The telescope was destroyed in the 2003 firestorm and now only the scarred shell remains in place.24cm x 19.5cmphotographb&wimage/tiffThis image is provided for research purposes only and must not be reproduced without the prior permission of the Archives Program, Australian National University.Commonwealth Solar Observatory (1924-1957)
