Observing events

Next public observing session 

Friday 11, Saturday 12 and Sunday 13 March at Ruislip Lido, 7–9 pm

Admission is free* and all are welcome!   

  The  Moon will be on view so you can study its craters as if you were flying over the surface! We'll also be able to see the famous Andromeda Galaxy, 2½ million light years away, as well as glittering star clusters and the  amazing Orion Nebula.

To help you know what telescopes are looking at we will place a white light under telescopes pointing at the Moon.  If weather permits looking at stars or galaxies operators will wear yellow or red armbands respectively.  Just remember when you change telescope to change colour as well!

 Bring your family and friends. Members of WOLAS will be on hand with a variety of telescopes and will be able to answer any questions you may have.

Don’t forget to wear warm clothing and bring a torch. Please switch it off when asked to. To prevent dazzling observers please limit the brightness of your torch once past the tea room to your phone’s light or equivalent.

In the event of poor weather the event will be cancelled, but please check the home page of this website  before leaving. We will announce GO/NOGO by 4 pm at the latest.  The tea house will not be open but we hope the toilets will be.  Please wear a mask and observe social distancing as best you can.  Members are volunteering to give up their time – but not give up their good health! 

* Admission to the event is free of charge, but Council parking charges of £3.50 apply to non-Hillingdon First Card holders until 8 pm.

How to get there

Ruislip Lido is off Bury Street, and access is via Reservoir Road, HA4 7TY. Park at the car park* at the end of Reservoir Road and be prepared to walk about 200 m along the well-surfaced road to our observing site, which is accessible to wheelchairs. The road is unlit so you may need a torch.
