All taken by James Nasmyth and separatef from his original album.
Photograph (calotype print) by James Nasmyth (1808-1890), taken 1858-1864, which originates from his album. The calotype print shows Warren De La Rue's (1815-1889) 13-inch reflecting telescope in its observatory at Cranford, Middlesex in England. A pioneer of astrophotography, De La Rue used this telescope to take a series of early photographs of the Moon. A difficult task, as the then available wet collodion plates were insensitive to light compared to modern films. This required exposures of several minutes through his telescope using a clock-driven equatorial mounting.
