Part of Compilation of Pogson's observations and drawing

This item was about the Norman Robert Pogson in 1861. N.R. Pogson was appointed the government astronomer at Madras, India. When he arrived he had to work under harsh conditions. He found the instruments in a bad shape and there were no proper staff to assist him. In spite of all these he began a series of observations which terminated with his death 30 year later. He as credited with 50,000 observations most of which were published by Michie Smith after Pogsons death. During his stay in Madras he discoverd several minor planets and detected large number of variable stars. He named his daughters after the minor planets he discovered. He was also well known for his work in comets and solar eclipses.
