Moon crater

Lithographic colour print issued by Harvard College Observatory in 1876, showing three sketches of craters on the Moon (Torricelli, Agrippa with Godin and Eratostenes). Produced in 1872 by …tienne LÈopold Trouvelot, a French artist, these views were produced using the observatory's 15-inch refracting telescope made by Merz of Munich, Germany. At this time, drawings made at the telescope using only the eyes showed more detail than could be produced using the insensitive photographic plates then available.

Eclipse of the Sun, 7 August 1869

Lithographic colour print issued by Harvard College Observatory in 1876, showing the corona around the Sun during a solar eclipse. The pearly and ghostly light is only seen during the brief period of totality when the Moon blocks the dazzlingly bright surface of the Sun. The corona forms the outer and very tenuous atmosphere of the Sun, an envelope of highly ionised gas, superheated to over a million degrees centigrade. Etienne Léopold Trouvelot, a French artist, made these sketches during the solar eclipse of 7 August 1869 from Shelbyville, Kentucky in the United States © The Royal Photographic Society Collection at the V&A
