and as ever, we'll have a range of beautiful astronomical postcards to buy to decorate your home or send to your friends!
Check out the timelapse video of a previous Open Afternoon below! Can you spot Doctor Who and the dalek? How about Cybermen? Even Einstein and Newton make an appearance! If you attended the 2015 event, see if you can spot yourself! If not, don't miss out on the fun this year!
