Bonjour,
\napr\u00e8s pr\u00e8s de 2 ans, j\u2019ai enfin eu l\u2019occasion de ressortir mon instrument. J\u2019ai donc choisi la n\u00e9buleuse de la Rosette, une magnifique cible du ciel d\u2019hiver bien connue, que je me devais d\u2019essayer avec des filtres \u00e0 bande \u00e9troite. <\/p>\n

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

Il s\u2019agit d\u2019une composition en HOO pour les n\u00e9bulosit\u00e9s et RGB pour les \u00e9toiles. La n\u00e9buleuse et les \u00e9toiles ont \u00e9t\u00e9 d\u00e9velopp\u00e9es s\u00e9par\u00e9ment gr\u00e2ce \u00e0 StarNet2 et combin\u00e9es en toute fin de process.<\/p>\n

Prises r\u00e9alis\u00e9es entre le 25\/02 et le 04\/03 2022 sur 4 nuits.
\nHalpha : 4h15 en sub de 300s; OIII : 4h30 en sub de 600s; R, G et B : 36 minutes en sub de 180s.
\nNewton Quattro 10\u201d F\/4, Paracorr 2\u201d, Moravian G3-16200 @ -20\u00b0C, filtre CLS.
\nLieu : Genval.
\nTraitement : PI, StarNet2 & Affinity Photo (image r\u00e9duite \u00e0 50%).<\/p>\n
