Your private Night at the Cronyn Observatory

Volunteers at The Hume Cronyn Memorial Obseratory of Western University, Canada

Astronomy Public Nights at the Cronyn Observatory occur weekly during May though August (every Saturday evening, 8:30-11pm), and monthly during October through April.

General Information:

Our public nights are first and foremost a time to view the skies through our telescopes and to pose your favorite questions to the astronomers hosting the evening. Objects viewed vary with the season, but might include the Moon, Venus, Mars, Jupiter, Saturn, binary stars, star clusters, planetary nebulae, or galaxies. There is nothing like seeing these wonders with your own eyes!

There will also generally be a presentation of general astronomical interest to be held in the lecture theatre at one or more times during the evening. We often will also open up our 1940 and 1967 period rooms to the public, as well as our astronomical demo vault in the basement. 

In the event of cloudy skies, the observatory will still be open for the presentation, demos and a look at the telescopes, but closing time might be earlier. Note that our weekday public nights are stargazing only -- no presentation.

Members of the Royal Astronomical Society of Canada are also on hand with their portable telescopes set up on the Observatory balcony and  front lawn. If you're interested in doing some astronomy as a hobby, these are the people to talk to.

There is no charge, and no reservations are necessary; come and go as you please throughout the evening. The University has free parking on the weekends; check the "Visitor Parking" link.

Fall/Winter Schedule:

The observatory is typically open about twice a month during the fall/winter and on special occasions; check our calendar on our main page. Note that Fall/Winter public nights start earlier and are shorter than our summer public nights -- check the schedule for details.

Summer Schedule:

The Observatory is open every Saturday evening during the months of May, June, July, and August.

Start time is 20:30 (8:30 p.m.). Closing time is 23:00 (11:00 p.m.).

The first summer public night for 2020 will be on Saturday, May 2; the last will be August 29.
