Quénisset u. Edward Emerson Barnard, Ferdinand-Jules

Bedeutende Sammlung von 91 frühen Astrophotographien. Ca. 1900-1930. Vintages, Bromsilberdruck. Teils auf Agfa Brovira oder Agfa Lupex. Maße von ca. 3 x 3 cm bis 24 x 18 cm.

Der Franzose Ferdinand Jules Quénisset (1872-1951) und der Amerikaner Edward Emerson Barnard (1857-1923) waren bedeutende Astronomen der Jahrhundertwende und Pioniere der Astrophotographie. Beide machten wichtige Entdeckungen durch Beobachtungen, die auf ihren Photographien beruhten. Quénisset ist der Urheber von nahezu 6000 astronomischen und mehr als 1500 meteorologischen Photographien. Barnard stellte eine Liste von 182 Dunkelnebeln zusammen, die als Barnard Catalogue of Dark Markings in the Sky oder Barnard-Katalog bekannt ist. - Die vorliegende Sammlung lässt sich nach den beobachteten und aufgenommenen astronomischen Themen in 8 Gruppen unterteilen: s.u. - Teils verso mit Spuren früherer Montierung. Einige mit leichten Aussilberungen. Insgesamt sehr schön erhaltene und dokumentarisch wichtige Sammlung.

Important collection of 91 early astronomical bromide prints. Ca. 1900-1930. The Frenchman Ferdinand Jules Quénisset (1872-1951) and American Edward Emerson Barnard (1857-1923) were two major astronomers of the turn of the 20th century and pioneer astrophotographers. Both made important discoveries from observations based on their photographs. Quénisset took nearly 6000 astronomical photographs and more than 1500 meteorological photographs. Barnard compiled a list of 182 dark nebulae known as the Barnard Catalogue of Dark Markings in the Sky, or Barnard Catalogue. The collection can be divided into 8 groups according to the astronomical subjects observed and photographed: 27 photographies of the moon: - 3 later reprints of photos originally captioned and dated by Quénisset, 25 October 1899 (last quarter moon), 23 October 1902 (last quarter moon) and 12 September 1903 (waning gibbous moon). - 2 photos of the moon, ca 1900-1910, with autograph annotations and signature on the reverse. - 6 full moons (some with reverse captions : Nov. 1903, March 1907, April 1909, 26 August 1904). - 2 quarter moons and 2 gibbous moons. - 1 close-up of craters. - 11 smaller photos showing the cycle of the moon, one dated 23 February 1909. 16 photographies of the Milky way and galaxies: - Probably 8 by Quénisset : 3 of the great Andromeda nebula, including 2 with autograph annotations and signature on the reverse, one of the Orion Nebula, captioned and signed by Quénisset, one of the constellation Gemini captioned and signed by Quénisset, one of the Whirlpool Galaxy, also known as Messier 51a, one of Messier 81 and one unidentified galaxy. - The 8 other photos probably by Barnard, including 3 with captions in pencil on the reverse. - 25 photographies of the Sun and sunspots: - 10 photos captioned and signed in pencil by Quénisset on the reverse sides, August 1908-September 1926. - 7 uncaptioned photos including one of a total solar eclipse. - 8 smaller photos of sunspots. 11 photographies by Quénisset of Jupiter and satellites: 1922-1931, including 3 with autograph annotations and signature on the reverse and 4 smaller photos. - 2 photographies of Mars: probably from the series taken by Barnard on 28 September 1909. - 3 photographies of comets: - 2 of them on Agfa Lupex paper. - The smaller shows the comet Brooks in 1911. Inscription in pencil on the reverse. - 3 photographies of Saturn. - 4 meterological photographies of clouds: ca 1920-1930, probably by Quénisset, 2 on Agfa Lupex paper. - - Some with traces of earlier mounting on verso. Some with slight silvering. Overall a very beautifully preserved and documentarily important collection.
