As a volunteer at the David Dunlap Observatory in Richmond Hill, Ontario, Canada, I adopted the moniker Stu Starwalker. My passion for observational astronomy led me to nightscape photography. In 2018 I broadened my photography interest to add daylight, mostly landscape, imaging.

All my Flickr images are uploaded at low resolution and high compression. High quality, full resolution images are available by contacting me directly at ggstu12 at gmail.
