Je proposais hier quelques images faites avec un filtre dual-band (IDAS NBX).
\nPour comparaison, voici un des objets (NGC8992, Dentelles du Cygne), captur\u00e9 avec le m\u00eame \u00e9quipement \u00e0 l’exception du filtre.
\nIci c’est un filtre IDAS LPS P2 (suppression de la pollution lumineuse). Image RGB donc.
\nC’est le r\u00e9sultat de 245 images de 1 minute, prises entre le 22\/7\/2020 et le 21\/10\/\/2020…
\nJ’ai choisi une orientation finale proche de la pr\u00e9c\u00e9dente; ce sont \u00e0 l’origine des essais pour trouver la distance optimale capteur\/r\u00e9ducteur, pas mal d’images individuelles ne sont donc pas vraiment top et je n’ai pas fait de tri.<\/p>\n

NGC6992 en RGB, 50 % de la taille originale, jpeg 60.<\/p>\n
