TO mark its 50th anniversary year, West of London Astronomical Society is inviting people to join them observing the moon and stars at Ruislip Lido on Friday, Saturday and Sunday, October 27-29, 6-8pm.

Early on, Saturn with its rings will be visible through the telescopes and, if it is clear enough, members will also be viewing star clusters such as the Pleiades or Seven Sisters, coloured stars such as the famous Betelgeuse (a red giant star which could explode soon), double stars and distant galaxies such as the Andromeda Galaxy, the Milky Way’s nearest neighbour at two million light years distant. 

David Arditti, WOLAS vice-president, said: “People, especially children, first shown the moon through an astronomical telescope, often remember the experience for the rest of their lives.

“To see the razor-sharp, airless landscape, with its craters, great plains, mountains and rilles illuminated by the low sun is something spectacular and unique.

“We have chosen some dates when the moon will be well-placed for observing, but not so bright as to drown out the fainter objects in the sky. All we can do now is to hope for clear skies!"

Visitors are advised to take warm clothing as it could be chilly. The event is suitable for all the family. 

There is no admission charge, but there may be a charge for parking in the Lido car park. In case of doubtful weather, check the WOLAS website,, where the society will make an announcement on whether the event is on or not each day.

Ruislip Lido is off Bury Street. Entry is via the gate adjacent to the free car park at the end of Reservoir Road, HA4 7TY. You can get there on the H13 bus.
