The artificial lighting of our cities greatly affects the darkness of the sky. It is increasingly difficult to find observation sites without light pollution. For deep sky photography, it is still possible to take beautiful images in a site where light pollution is high.
This section will present images taken at my permanent observatory in Longueuil where light pollution is extreme (white area) and in sites without any light pollution (gray and black areas). I also present some images that I made of the solar system.
