Bonjour,
\nle titre fait r\u00e9f\u00e9rence aux jets d’hydrog\u00e8ne bien sur. M82 n’est pas la seule \u00e0 avoir ce type de jets, mais c’est la plus spectaculaire. La galaxie du cigare est en interaction avec sa voisine M81, ce qui provoque un sursaut de formation d’\u00e9toiles et l’\u00e9mission de ces jets d’hydrog\u00e8ne.
\nL’image que j’en pr\u00e9sente ici a \u00e9t\u00e9 captur\u00e9e depuis La Fosse sur 2 nuits, les 03 et 04\/03\/2022 avec la ST10XME sur le C11 \u00e0 F\/D 6,3. Il s’agit d’une composition (H\u03b1)H\u03b1vb pour laquelle il y a 10 x 5 minutes plus 10 x 1 minute pour les couches H\u03b1 et verte (la couche H\u03b1 sert de couche rouge dans la RVB) et 12 x 5 minutes plus 12 x 1 minute pour la couche bleue; le tout combin\u00e9 \u00e0 40 poses de 5 minutes en binning1 avec filtre H\u03b1 de 13nm de bande passante pour la luminance; le temps de pose global retenu est donc de 9 heures et 2 minutes. Le pr\u00e9traitement a \u00e9t\u00e9 fait avec CCDSoft et je viens de reprendre le traitement avec Pixinsight et PSP X9 et Photoshop CS2 pour les finitions. <\/p>\n
