Online Map of Toothill

The club's observatory at Toothill is located in a relatively dark site just outside Southampton, see map below.

It has reopened to the public on the dates to the left.   You will see that weekend sessions are now arranged in pairs, with a "primary" and a "back-up". The primary will take place, weather permitting, but the back-up will only take place if the corresponding primary sessions were both clouded out. Each session is open ended, we stay until we've had enough or the weather closes in.

No need to book, just turn up.

Members admitted free.  Non-members: adults £5,  children free.

Cash payments only, please. No cards

Toilets and free parking are available.

The observatory contains:

  • 14" Meade telescope
  • 8" Meade LX90
  • 6" Celestron Nexstar SE
  • 20 x 80 binoculars
  • Computer with desktop planetarium

The design of the 14" telescope is such that users remain seated, so it is suitable for wheelchair users.
