Français : Filé d'étoiles centré sur l'Étoile polaire et montrant des étoiles circumpolaires. L'image a été réalisée dans la réserve faunique des Laurentides (km 193) à l'aide d'un Canon EOS 600D défiltré sur trépied fixe et équipé d'un objectif fisheye. Le temps d'exposition est de 30 minutes, ce qui permet de percevoir le mouvement apparent des astres, qui se déplacent dans le sens antihoraire. On peut aussi apercevoir la lumière urbaine de Saguenay et des traces d'aurores polaires (dans le bas de l'image) ainsi que la Voie lactée (de la droite de l'image jusqu'en haut à gauche). |
