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!

UofT Planetarium: The Life and Death of Stars

Showtimes: 7:00pm, 8:10pm, 9:15pm The stars in the night sky seem unchanging and eternal, and have remained the same for the history of human civilization. However, over millions and billions of years, new stars are born, live out their long lives, and eventually die in a blaze of glory. In this show, we will be exploring the lives of stars by visiting stellar nurseries, supernova remnants and much more!

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.

Hamilton Amateur Astronomers: Introduction to Deep-Sky Image Processing with PixInsight

PixInsight has become a popular image processing software package in recent years, especially for deep-sky astrophotography. Ron Brecher has used PixInsight for all of his deep sky processing since 2009. In this demonstration, Ron will show you how you can reveal the hidden treasures in your deep-sky images with just a few processing steps: crop bad edges, correct gradients, balance the colour, supress the noise, “stretch” the histogram and adjust colour, brightness and contrast.
