Hello,<\/p>\n

Voici le r\u00e9sultat final de 20h15min de pose r\u00e9partie en 96x300seconde filtre D1 (HA_OIII) 40x360sec+99x300sec filtre D (SII_OIII)<\/p>\n

Pour le traitement j’ai utilis\u00e9 une technique particuli\u00e8re propos\u00e9e par A.Block<\/p>\n

Extraction des couches HA, OIII et SII \u00e0 partir des deux images r\u00e9sultantes issues des deux filtres.<\/p>\n

Fonction DBExtract dans Pixinsight. C’est un script propos\u00e9 par Ra\u00f9l Hussein qui tient compte du capteur et du type\/marque de filtre utilis\u00e9.<\/p>\n

Cr\u00e9ation d’une image HOO apr\u00e8s tous les traitements habituels de r\u00e9duction du gradient, r\u00e9duction de bruit, convolution, etc.<\/p>\n

Colorisation de l’image SII et augmentation du contraste dans les zone les plus brillantes en SII<\/p>\n

Mixage de l’image SII obtenue avec la HOO pour obtenir la version SHO.<\/p>\n

Divers ajustements de contrastes, saturation et bruit avant r\u00e9-int\u00e9gration des \u00e9toiles extraites des deux images de base et recombin\u00e9e avec les script de SetiAstro NB to RGB stars pour obtenir des couleurs d’\u00e9toiles raisonnables.<\/p>\n

Combinaison de la SHO starless et des \u00e9toiles avec la fonction Screen Stars toujours dans PI.<\/p>\n

Image resampl\u00e9e \u00e0 33% de l’originale<\/p>\n

Recadrage sur Pacman en full resolution<\/p>\n

Idem sur SeWb1<\/p>\n
