bonjour,<\/p>\n

Abell 39 est une tr\u00e8s belle n\u00e9buleuse plan\u00e9taire situ\u00e9e dans la constellation d’Hercule. Sa distance \u00e0 la terre est estim\u00e9e \u00e0 6800 ann\u00e9es-lumi\u00e8re. Elle est presque parfaitement sph\u00e9rique et c’est aussi l’une des plus grande plan\u00e9taires connue avec un rayon d’environ 2,5 ann\u00e9es-lumi\u00e8re.<\/p>\n

Le champ entier \u00e0 70% de la taille:
\n\"\"<\/a><\/p>\n

Et un crop \u00e0 la taille d’acquisition:

La photo pr\u00e9sent\u00e9e ici a \u00e9t\u00e9 r\u00e9alis\u00e9e ce samedi 3 mai 2014 depuis La Fosse avec la camera CCD Sbig ST10XME plac\u00e9e au foyer de la lunette Televue NP101IS. 8 poses de 15 minutes \u00e0 travers un filtre Ha de 6nm et 10 poses de 15 minutes \u00e0 travers un filtre OIII de 12nm de bande passante (Merci Oli npour le pr\u00eat) compose cette vue. Apr\u00e8s un pr\u00e9traitement classique des poses sous CCDSoft, l’assemblage des couches RVB a \u00e9t\u00e9 r\u00e9alis\u00e9 sous Photoshop CS2 en mode Ha OIII OIII pour lequel la couche OIII a \u00e9t\u00e9 dupliqu\u00e9e.
\nRemarque: la n\u00e9buleuse est fortement d\u00e9centr\u00e9e dans l’image du champ entier en raison de la n\u00e9cessit\u00e9 d’avoir une \u00e9toile guide suffisamment brillante sur le capteur de guidage int\u00e9gr\u00e9 de la ST10 utilis\u00e9e avec des filtres \u00e0 bande \u00e9troite.<\/p>\n
