Many of these photographs are previously unfamiliar and give insight into the history of Sydney Observatory. They include photographs of Pennant Hills (Red Hill) Observatory, Sydney Observatory and the 1922 Sydney Observatory expedition to Goondiwindi in Queensland to observe a total solar eclipse. There are also interesting images of a 1908 eclipse trip to Tahiti. The photographs were taken by or were owned by James Short, who was in charge of the astrographic telescope at Sydney Observatory's Red Hill Branch from July 1890 until his retirement in 1930. He made important contributions to the work of the Observatory while his turbulent relationships with the various Government Astronomers add colour to the Observatory's history.
