Here's something to do on a Saturday afternoon in London. Get a boat down the river to Greenwich, have lunch in the park- preferably something purchased in the market - and then stroll up the hill to the Royal Greenwich Observatory and have a look at the history of Mankind's study of the stars.
In another building is the only planetarium in London and it's also the site of the Astronomy Photographer of the Year contest> always nicely presented with the pictures backlit in a dark room. You'll be surprised that a lot of these images were captured with easily available amateur equipment.
