An improved form of De La Rue's photoheliograph built by Dallmeyer was installed at Melbourne Observatory in time to observe the 1874 transit of Venus. Photographs obtained included some made with De La Rue's version of Janssen's rapid sequence photographic camera. A succession of adverse circumstances has led to the preservation of the photoheliograph at Melbourne, unaltered from its nineteenth century form. It is expected to be usable again in its original domed building for the 2004 transit of Venus.
