Dark Sky Star Party (GO for Monday)

See the milky way and galaxies with the unaided eye. Point your telescope to find the many dim deep space objects that sprinkle the sky. Away from Toronto's light polution, there is so much to see. We observe from the Long Sault Conservation area, an hour outside of Toronto. We meet around dusk once a month in the parking lot for views only seen in dark sky conditions. We hold this event on the first clear night of our week-long window, so the date and time are determined closer to.

OSC: Shoot the Moon Star Party

To the Moon and back! Show the Earth’s only natural satellite a little love by taking its picture with your smartphone or digital camera. As the second-brightest, regularly visible celestial object in our sky, photographing the Moon is a snap. (See what we did there?) Participate in an astrophotography workshop, take a tour of the night sky using a telescope, engage in hands-on, Moon-themed activities, find out about the latest in lunar science and learn about mathematician Katherine Johnson, whose calculations helped put the first humans on the Moon.

City Star Party (GO for Thursday)

Hover above the moon like an astronaut and get eye-to-eye with the planets. Find colourful stars, star clusters, bright nebulae and even another galaxy. Our monthly City Star Party is the place to catch universe from within the city limits at Bayview Village Park. If you don't have a telescope then you will find many astronomers who would love to share a view. If you are thinking of buying a telescope, viewing with other people's equipment is the best way to make a good choice. If you have a telescope or binoculars, please bring it!
