On the 21 September 1922 an eclipse of the sun passed across the centre of Australia providing optimum conditions for observations. This photograph was taken by one of the members of the Wallal Eclipse expedition in Western Australia.
Here there were three international parties, the Lick Observatory party, under the direction of W. W. Campbell, a group from the University of Toronto, under C. A. Chant and the Indian expedition supervised by J. Evershed. In addition Australia provided a fourth group from the Perth Observatory, directed Mr. Nossiter.
Amongst the 35 tons of stores and equipment unloaded at Wallal was a forty foot coronal camera which required supporting towers 36 feet high. This photograph of the eclipse during total pahse was taken by Dr. Adams using this astrograph.
