Bonjour,
\nUne image sans pr\u00e9tentions de l’amas ouvert M46 captur\u00e9e ce samedi 14 janvier 2018 depuis La Fosse avec le bon vieux Canon 350D modifi\u00e9 plac\u00e9 au cul du C11 \u00e0 F\/D 6.3. La pr\u00e9cision du suivi de la v\u00e9n\u00e9rable monture Takahashi NJP permettant des poses de 2 minutes \u00e0 1,76 m\u00e8tre de focale sans d\u00e9rive notable, j’ai pu faire 30 poses avant que l’amas ne soit trop bas sur l’horizon. Traitement complet sous IRIS et finitions sous Toshop CS2 et PSP X2 ainsi que PSP X9. Vu la faible hauteur de l’amas sur l’horizon au moment des captures, il a fallut recaler les couches l’une par rapport \u00e0 l’autre apr\u00e8s addition en raison de la dispersion atmosph\u00e9rique. l’image est pr\u00e9sent\u00e9e ici l\u00e9g\u00e8rement cropp\u00e9e et r\u00e9duite \u00e0 50% de la taille d’acquisition.
\nEnfin, la n\u00e9buleuse plan\u00e9taire NGC2438 visible dans l’image ne fait pas partie de l’amas. Elle est en avant-plan et c’est donc un simple effet de perspective.<\/p>\n
