Sky glow is one of the most significant consequences of light pollution, which not only disrupts the work of astronomers but also deprives city dwellers of the possibility of enjoying the beautiful night sky and nocturnal landscapes. Unfortunately, one must now travel several hundreds of kilometers from an urban centre to clearly see the Milky Way. Indeed, more than two thirds of Americans are not able to make out the Milky Way with the naked eye from their home. Almost 97% of stars are no longer visible from the major cities of the world. In the region of Montreal, one can see only about 100 stars, while it is possible to witness over 3,000 stars with the naked eye in the region of Mt. Megantic.
