OASI is a society for people interested in astronomy. We are based at Orwell Park Observatory and Newbourne Village Hall, both situated near Ipswich, Suffolk. Members enjoy a wide range of interests in astronomy and include armchair astronomers, casual observers, and dedicated amateurs with specialist skills in visual and photographic observing, constructing telescopes, public education in astronomy and the history of astronomy.
