Summary[edit]
DescriptionCircumpolaire au dessus de l'observatoire.png |
Français : Les filets d'étoiles sont obtenus grâce à une pose longue (plusieurs secondes à plusieurs minutes) durant la nuit. L'effet de filets est dû à la rotation de la Terre autour d'un axe nord-sud pointant vers l'étoile polaire (seule étoile qui ne fait pas de trainée).
Ici le filet d'étoiles est un assemblage de 70 photos de plusieurs secondes afin de ne pas avoir un premier plan surexposé. English: Star trails are the result of a long exposure (many seconds or many minutes) during the night. Trails are due to the earth rotation around a north-south axis pointing polar star (the one that doesn't makes trail). Here is a set of 70 pictures of many seconds exposition in order to have a foreground not overexposed.
