David Dunlap Observatory

Since 1935, this observatory has been a research centre for the University of Toronto's Department of Astronomy and Astrophysics and a facility for public education and outreach. A popular site for Doors Open Richmond Hill in 2019, the David Dunlap Observatory gives us a glimpse into the skies above us from a spectacular facility. During Digital Doors Open, take a virtual tour of the site through the video below. Also, enjoy a short history of the site from the Royal Astronomical Society of Canada. Or learn how to use a star finder to find your way around the night skies.
