Salut,<\/p>\n

le complexe Barnard 33 et plus sp\u00e9cifiquement la T\u00eate de cheval et la flamme. Mais aussi IC431, IC432, IC 435.<\/p>\n

Images enregistr\u00e9es sur deux nuits froides ces 09 et 10 janvier 2024.
\n12 x 600 secondes + 14 x 300 secondes. J’avais aussi 30 X 180 secondes mais je ne suis pas aper\u00e7u d’un probl\u00e8me de mise au point. Donc je ne les ai pas utilis\u00e9es.
\nT250\/1200 (PI me donne 1153mm lors du plate solve)
\nZWO ASI 2400 pro MC px de 5.94 microns
\nfiltre Alta\u00eer Tri-band<\/p>\n

Acquisition:<\/p>\n

Logiciel N.I.N.A avec prise en charge du focuser SestoSenso pour la mise au point. <\/p>\n

Suivi phd2 aussi coupl\u00e9 au logiciel d’acquisition.<\/p>\n

Traitement Pixinsight.<\/p>\n

Fonction :
\nPr\u00e9-traitement automatis\u00e9e WBBP
\nStar Alignement,
\nImage integration : Winsorized Sigma Clipping
\nDynamic crop pour supprimer les chevauchements (comble avec la t\u00eate de cheval..)
\nPlate Solve
\nSPCC (spectrophotom\u00e9trique color calibration)
\nBlureXterminator
\nNoise Exterminator
\nHistogram Transformation mont\u00e9e en histogramme
\nExtraction de la luminance
\nStar exterminator –> object mask et star mask
\nAjustement histogramme du mask objet et application sur l’image cible.
\nHDMRT pour att\u00e9nuation des hautes lumi\u00e8res
\nLocal histogram equailisation pour renforcer les contrasts dans les zones lumineuses.
\nSharpening tr\u00e8s l\u00e9ger.
\nCurve transformation pour accentuer les contrasts des couleurs.
\nApplication du star mask
\naccentuation des couleurs des \u00e9toiles.
\nRetrait du masque.
\nSCNR pour supprimer la l\u00e9g\u00e8re dominante verte de l’image finale.
\nR\u00e9duction de la taille pour confort de visualisation sur le site.<\/p>\n

Et c’est tout….<\/p>\n
