Photograph (calotype print) by James Nasmyth (1808-1890), taken around 1858-1865, showing his portable 13-inch reflecting telescope on the lawn in the grounds of his home at 'Hammerfield' in Kent, England. Nasmyth a successful industrialist and engineer made extensive observations of the Moon. Working from drawings, he calculated the height of the lunar features by measuring the length of their shadows. These were then photographed with suitable lighting to produce better results than could be achieved at the time using direct lunar photography. He went onto photograph a whole series of his lunar models. They were used to illustrate the book, 'The Moon' that Nasmyth published in 1871 with James Carpenter.
