Welcome to our site, your link to all that’s astronomical in Orpington, Bromley, Sevenoaks, and the surrounding area. Here you will find details of the Society’s activities. Come and join local enthusiasts discussing and enjoying the night sky!
Our regular monthly meetings are held at St Francis of Assisi Church Hall in Petts Wood. We meet every month, usually (except in December) on the fourth Wednesday of the month.
We hold observing evenings once or twice a month, usually starting at a pub or hall so that the sessions are not weather dependent.
From time to time we arrange dinners, barbecues, picnics, camps, outings and other special events.
