Le filtre ZWO Duo-Band est un filtre \u00e0 bande \u00e9troite double ; \u00e0 l’origine, il a \u00e9t\u00e9 d\u00e9velopp\u00e9 pour compl\u00e9ter les cam\u00e9ras ZWO ASI Color. Ce filtre s’adresse \u00e0 l’astronome qui poss\u00e8de d\u00e9j\u00e0 une cam\u00e9ra couleur et qui souhaite prendre des photos en utilisant la technique de la bande \u00e9troite sans qu’il ne lui faille acheter une cam\u00e9ra mono, une roue \u00e0 filtres et un jeu de filtres \u00e0 bande \u00e9troite.<\/p>\n

Le filtre Duo-Band permet un acc\u00e8s \u00e9conomique au monde de l’astrophotographie \u00e0 bande \u00e9troite et peut \u00e9galement constituer une solution pratique pour les zones urbaines pollu\u00e9es par la lumi\u00e8re. Le filtre permet le passage de la lumi\u00e8re aux longueurs d’onde H\u03b1 (656 nm) et OIII (500 nm) et r\u00e9duit la pollution lumineuse due \u00e0 la Lune ou \u00e0 l’\u00e9clairage public. Le contraste et la visibilit\u00e9 de nombreux objets du ciel profond (tels que les n\u00e9buleuses en \u00e9mission) sont nettement am\u00e9lior\u00e9s.<\/p>\n
