SES was started for conducting activities in observational astronomy, astrophysics, and aerodynamics. Subsequently, it was divided into 2 separate divisions to give justice to both of them under one roof - Aeromodelling and Astronomy & Astrophysics. The Astronomy and Astrophysics division specializes in astrophotography, observational astronomy, documentary watching sessions and all-round discussions on everything Space! The Aeromodelling division involves the designing, building and flying of miniaturized aircrafts, a hobby enjoyed widely by aviation enthusiasts.
