Bonjour, j’ai r\u00e9alis\u00e9 dans la nuit du 4 au 5 mai 2019 une prise de vue de Messier 101, une galaxie spirale dans la constellation de la Grande Ourse.<\/p>\n\n\n\n

L’objectif \u00e9tait double: v\u00e9rifier le r\u00e9glage du miroir secondaire du t\u00e9l\u00e9scope newton, tester les images en LRVB.<\/p>\n\n\n\n

Le setup: t\u00e9l\u00e9sope 154mm diam\u00e8tre et 600mm focale sur monture Orion Sirius sans autoguidage, cam\u00e9ra Zwo ASI 183 monochrome, correcteur de coma TSGPU et roue \u00e0 flitre Zwo.<\/p>\n\n\n\n

D’un point de vue technique, j’ai r\u00e9alis\u00e9 1h20 de poses en luminance, et 10 minutes de poses pour chaque couleur (rouge, vert, bleu) avec des poses unitaires de 20 secondes gr\u00e2ce \u00e0 cette cam\u00e9ra refroidie \u00e0 -18\u00b0c.<\/p>\n\n\n\n
