Open House

The Hallam Observatory is open to the general public one evening every month (see table below for dates and times).  If the skies are clear we provide a naked eye sky tour of the stars and constellations and use the telescope to view the Moon and any planets that may be visible at that time as well as some deep sky objects (star clusters, galaxies, etc.).  Please note that this event is "weather permitting" and although our telescopes are powerful they cannot see through clouds.  The site has plenty of parking however it is not plowed in the winter and if there is snow on the ground access can be limited. 

IMPORTANT NOTE: The Hallam Observatory grounds are private property and no trespassing is allowed. Other than the open house nights the site is closed to the public.

The RASC - Windsor Centre also offers private group observing sessions to the public. The fee is $5 per person with a minimum of $40. To find out more about setting up a private observing session for your group please contact us.

RASC - Windsor Centre members can have exclusive access to the observatory by paying the annual access fee of $60 (plus a one-time key deposit of $10). Also, if you use the observatory site and find it of value we have a voluntary support fee of $20 that helps offset the cost of maintaining the site.
