Legacy Astrophotography: The Taurus Dark Cloud

Classic black and white astrophotography using modern orthopanchromatic b&w emulsion.

The image was obtained by using an equatorial mount for tracking during the 60 minute exposure utilizing a Pentax 67 and 105mm f/2.4 lens stopped down to f/4.

Under a dark sky these dark regions in Taurus and Auriga can be glimpsed by the keen observer. Long exposure photographs show an entanglement of dark nebulae rivaling anywhere else in the northern Milky Way. Edward Emerson Bernard was among the first to photograph this region and was delighted by what he recorded.

Barnard photographed this region (Plate 5) on January 9, 1907 revealing more than what can be seen here.
