Depuis mon jardin la nuit de dimanche \u00e0 lundi; pas un ciel de n\u00e9buleuses, je choisi donc du LRGB : vignettage, gradients marqu\u00e9s, bref la joie \u00e0 traiter et je n\u2019y arrive pas bien\u2026
\nDans la Grande Ourse, le couple M97 et 108 (pour changer de M81 et M82) :<\/p>\n

\"\"<\/a><\/p>\n

2 heures de pose au total, poses individuelles de 5 minutes, toutes en binning 1×1.
\nSi les couleurs peuvent para\u00eetre bizarre, c\u2019est peut \u00eatre parce que je me suis tromp\u00e9 de filtre : je voulais mettre un Baader Moon & Skyglow, mais j\u2019ai mis l\u2019UHC \u00e0 la place\u2026
\nCourbes dans photoshop, deblooming \u00e0 la main, j\u2019ai cr\u00e9\u00e9 un calque en produit avec un \u00e9clairage pour tenter d\u2019\u00e9liminer le vignettage, les flats du lendemain sont inexploitables.<\/p>\n

Luminance: 12×5 minutes
\nRouge: 4×5 minutes
\nVert: 4×5 minutes
\nBleu: 4×5 minutes
\nLunette AP 130 @f\/7
\nMonture AP 900 GTO
\nCam\u00e9ra SBIG ST-10XME<\/p>\n
