Observing events

Next public observing session 

We will be holding public observing sessions at Ruislip Lido on Friday 27, Saturday 28 and Sunday 29 October 2017 between 6 pm and 8 pm each evening . Admission is free, and all are welcome!

 The half 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 Seven Sisters star cluster, the Ring Nebula and  maybe even the Andromeda Galaxy., 2½ million light years away.

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!

Admission to the event is free of charge. 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.

On nights when observing is possible the Turntable tea room will be open for refreshments, courtesy of the Lido Railway. Toilets are also available.

In the event of poor weather the event will be cancelled, but please check the home page of this website on the night if you are unsure.

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.

* Parking charges may now apply, due to a change in Hillingdon Council policy. The Reservoir Road car park is now split between the council and The Water's Edge pub:

Council parking is free for Hillingdon resident card holders, £3.50 otherwise (24h/24h)

The pub car park is free for customers but you must register at the bar within 15 minutes of arrival and there is a 2h time limit.
