Bonjour,
\nles nuits sont tr\u00e8s courtes en ce moment, mais j’ai quand m\u00eame eu le temps de capturer le c\u00e9l\u00e8bre anneau ce mercredi 3 juin dernier.
\nBien sur le temps de pose total est assez court puisqu’il n’est que de 2heures et 9 minutes.
\nDonc, image r\u00e9alis\u00e9e depuis La Fosse avec le C11 avec r\u00e9ducteur de focale F\/D 6,3. IL y a 30 poses bleues, 21 poses vertes et 28 poses rouges toutes de 1 minutes en binning 2×2 pour constituer l’image RVB; le tout combin\u00e9 \u00e0 50 poses \u00e9galement de 1 minutes, mais cette fois en binning 1×1 pour la luminance. Traitement complet darks et flats sous CCDSoft puis combinaison et finition sous Photoshop CS2 et Paint Shop Pro X2 et Seven.
\nEnfin, j’ai effectu\u00e9 un recadrage de l’image pour en diminuer le poids et pouvoir pr\u00e9senter la n\u00e9buleuse \u00e0 sa pleine r\u00e9solution.<\/p>\n
