🔭 More than 200 attendees joined us on Blackheath on Sunday 4 October, including students from the UCL Space Society. Saturn was the main visual highlight, with plenty of enthusiastic reactions at the eyepieces. Albireo and the Double-Double were among the other visual targets, while our smart scopes captured galaxies M31, M81, M82 and NGC 891, plus the Dumbbell Nebula. Thank you to everyone who came along, and to our volunteers for sharing the views and answering questions throughout the evening. Next session: Saturday 17 October, with Sunday 18 October as the weather back-up. Free and all welcome! Check flamsteed.info for details and confirmation before travelling. #Blackheath #Stargazing #Astronomy #London #Flamsteed
