Star trails over Toronto, ON showing their vibrant colours, are seen in this image taken on Oct 28, 2019 on the shores of Lake Ontario. The orange glow of Aldebaran can be seen in the trail on the bottom right, with the multiple star trails of the Pleiades cluster streaking towards the upper right of the image.
This picture is a part of a larger time-lapse and was taken with a Canon 6D at ISO 200 using a 50mm lens at f2.8. The images were processed in Photoshop and StarStax to produce the trails. The entire time-lapse can be viewed at https://www.youtube.com/watch?v=L4sgul-helQ.
