NGC 7331 est une grande galaxie qui se situe dans la constellation de P\u00e9gase. J’esp\u00e9rais pouvoir en sortir un peu plus de d\u00e9tails mais les conditions d’acquisition n’\u00e9taient pas tr\u00e8s bonnes et cela reste une cible un peu petite pour ma courte focale et le grand capteur de l’APN. Je pensais n\u00e9anmoins pouvoir faire une meilleure photo. Cependant l’avantage du grand champ est de montrer un grand nombre de galaxies pr\u00e9sents sur cette image, et notamment en bas \u00e0 gauche le Quintet de Stephan, qui est un amas de galaxies que l’on distingue (plus qu’on ne le voit) sur la photo. Un petit coup d’astrom\u00e9trie avec PixInsight nous montre le nombre de galaxies pr\u00e9sents sur la photo. Je me suis amus\u00e9 \u00e0 faire un petit crop sur le Quintet, m\u00eame si on ne voit pas grand chose (\u00e0 part un probl\u00e8me d’optique avec des \u00e9toiles bien allong\u00e9s en bas \u00e0 gauche de l’image ! …)<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
