Fessenkov & Rozhovsky - 7 Gasous Dust Nebulae & Telescope Photographs Description of the work: Included in this lot: Large Meniscus Telescope of the D. D. Maksutov System Gasous Dust Nebulae Photograph [The disintegration of a filament into stars in the southern and central part of the nebula NGC 6992-5] Gasous Dust Nebulae Photograph [The Horsehead region near S. Orion] Gasous Dust Nebulae Photograph [The disintegration of a filament into individual stars in the nebula NGC 6992-5 in the constellation Cygnus] Gasous Dust Nebulae Photograph [The disintegration of filaments into stars in the southern part of NGC 6992-5, Gas condensations south of NGC 6992-5] Gasous Dust Nebulae Photograph [The northern part of the unnamed filamentary nebula in the constellation Cygnus] Gasous Dust Nebulae Photograph [The central part of the nebula NGC 6611, Glowing rims in the nebula IC 1396, A luminous rim in an unnamed nebula in the constellation Emen] Description of the work: This scarce original photograph is from an album entitled Atlas gazovo-pylevykh tumannostei [Atlas of Gaseous Dust Nebulae]. The collection was created by Vasiliy Grigorevich Fessenkov & Dmitry Alexandrovich Rozhkovsky. It was published in 1953 in Almaty, Astrophysical Institute, Academic of Sciences of the Kazakh, SSR (Kazakhstan, USSR). This is a truly impressive mounted photograph from 1953 with accompanying text page. The text and photos were compiled by Vasiliy Grigorevich Fessenkov & Dmitry Alexandrovich Rozhkovsky. The pair pioneered the studying of gaseous nebulae. Fessenkov & Rozhkovsky were leading Soviet astrophysicists. They began their study of gas-dust galactic nebulae in 1950 and created these photographs. They began the study in order to understand "evolution of structure of nebulae, turbulent phenomena in interstellar clouds and in the vicinity of hot stars." The high-quality photographs illustrated the fine structure of objects formed by the radiation of ionised gas and made it possible to reveal dust scattering the light of stars. Their work was important and the field and inspired further interest in nebulae study. Rozhkovsky discovered 30 new diffuse nebulae.
