拍品描述

Included in this lot: Gasous Dust Nebulae Photograph [Nebula NGC 6618 in the constellation Sagittarius] Gasous Dust Nebulae Photograph [Gas nebula MCD 12 in the constellation Cygnus] Gasous Dust Nebulae Photograph [Gas nebula NGC 2327 in the constellation Monoceros] Gasous Dust Nebulae Photograph [Nebula NGC 1499 in the constellation Perseus] 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.
