CASCA-Westar Speakers

The following Canadian Astronomers are volunteers with the CASCA-Westar Lectureship series. Hailing from across the country, and varied in their interests, these astronomers bring their passion for what they do to the public through events such as public lectures, star parties and classroom workshops. Many have also been amateur astronomers.
