You can find lots of information about us on this website in the about us section and also about our previous meetings and events. If you have any further questions, please use the contact us section. If you’re undecided about joining please feel free to come along to one of our pub evenings and meet some of the members (see the Home page for dates). The Flamsteed provides excellent value for money. We support the work of the Royal Observatory Greenwich (ROG) through donations of our time, equipment, and money, while enhancing the knowledge, experience and enjoyment of astronomy for our members through a programme of first-class lectures and other events. We have access to the professional astronomy staff at the ROG as well as enjoying a world heritage site and the equipment and facilities of the ROG and National Maritime Museum.
