Voici les deux c\u00e9l\u00e8bres amas photographi\u00e9s depuis le Champ du Feu, situ\u00e9 \u00e0 1000 m\u00e8tres d’altitude dans les Vosges le 16\/09\/07 avec la ST10XME plac\u00e9e au foyer de la Genesis (D 101mm et F 540mm). L’image pr\u00e9sent\u00e9e ici a \u00e9t\u00e9 obtenue en combinant en mode RGB 19 poses dans le rouge, 10 dans le vert et 17 dans le bleu, toutes de 2 minutes en binning 1×1. Pr\u00e9traitement par soustraction des darks puis division par les flats suivie de la registration et addition sous CCDSoft puis finition sous PSP7. J’avais \u00e9galement fait un jeu d’images avec le filtre luminance, mais en seulement 2minutes de poses, le blooming \u00e9tait rh\u00e9dibitoire, rendant les prises inutilisables, m\u00eame apr\u00e8s traitement sp\u00e9cifique. Il faut \u00e9galement noter le manque de poses dans le vert. Cela est d\u00fb au vent fort qui soufflait en rafales cette nuit et qui m’a fait perdre bon nombre de captures.
