We are Astronomical Association Sofia, a non-governmental and non-political organization established in February 1994. The founders are
astronomers worked in Sofia National Observatory until its closure in 1992 and their many students. Our main idea is to create a place
where people from different ages with an interest in astronomy can obtain additional and informal education in astronomy, read specialized
literature and have access to astro equipment, and of course the pleasure from club meetings with supporters.
Our official WEB site where you can learn more about us, find interesting articles on astronomical topics, read the latest news from leading
international scientific organizations concerning upcoming celestial events, found good astro products, including telescopes and accompanying
accessories and inform about upcoming meetings and other events organized by us or with our participation.
