Photographic negative, the stars showing the area around Eta Argus (now Eta Carinae), glass / gelatin emulsion, used at Sydney Observatory, photograph by James Short and H. C. Russell, 30 December, Sydney, 1891
In 1887 H. C. Russell, Government Astronomer at Sydney Observatory, agreed to be a part of a photographic project of international significance. This was the 'Carte du Ciel' or ''Mapping the Stars'' project which saw Australian observatories engaged in mapping of the stars in the southern section of the heavens using photography.
A special photographic telescope, often referred to as the 'Star camera', was made for the project by and June 1891 the was complete except for the special measuring plates (resaux) which were needed to put lines of measurement onto the photograph.
This glass plate while among the first taken with the 'Star Camera' was not used on the ''Mapping the Stars'' project because the observatory did not have a tested reseau to use. Instead this plate is among a very few surviving early photographs made in 1891, using a reseau provided to Russell by Admiral Mouchez, the Director of the Paris Observatory.
