He then took an interest in astronomical photography and in 1883 he received a master's degree for techniques in determining the brightness of white stars. He invented techniques which are now used in theZöllner-Tserasky photometer. He began to teach in the Higher school for women from the 1870s and married the astronomerLidiya Petrovna Shelekhova in 1884. Lidiya is known for discovering numerous variable stars. He became a professor of astronomy in 1889. In 1890 he became director of the Moscow observatory. He retired in 1916 inFeodosia, Crimea but returned to live with his son in Moscow where he died.[1]
