Bonjour \u00e0 tous,<\/p>\n

Comme bon nombre d’entre nous, je me suis mis \u00e0 la couleur. J’utilise ici des filtres de chez Baader de couleur orange (570 nm), verte (500 nm) et bleue (435 nm). Les deux exemples pr\u00e9sent\u00e9s sont la n\u00e9buleuse Dumbell (M27) photographi\u00e9e dans la nuit du 14 Juillet 2005 et la galaxie des Chiens de Chasse (M51) le soir du 18 Juillet 2005 depuis mon observatoire \u00e0 Paradis (afin d’immortaliser, moi aussi, l’apparition de la SuperNova SN2005CS)<\/p>\n

Tous les clich\u00e9s ont \u00e9t\u00e9 pris au foyer Newton du CN212 ouvert \u00e0 F3.9 \u00e0 l’aide de l’Audine \u00e9quip\u00e9e du KAF401-E, le tout mont\u00e9 sur la monture EM200 sans autoguidage. Les poses individuelles sont de une minute chacune et la correction du noir est appliqu\u00e9e.<\/p>\n

Ces deux clich\u00e9s r\u00e9sultent d’un traitement LRGB sur base d’un compositage m\u00e9dian de 30 poses pour la luminance et de 10 poses pour chacun des 3 canaux couleurs. Ces r\u00e9sultats sont encourageants et d\u00e9montre la capacit\u00e9 de ces filtres \u00e0 enregistrer l’information couleur en astrophoto.<\/p>\n
