Bonjour,
\nJe vous pr\u00e9sente un clich\u00e9 du r\u00e9manent de supernova Cassiop\u00e9e A. Situ\u00e9 \u00e0 environ 11000 ann\u00e9es-lumi\u00e8re de la Terre, l’\u00e9toile responsable du r\u00e9manent a probablement explos\u00e9 en 1680, ce qui en fait un r\u00e9manent tr\u00e8s jeune. Il n’a pourtant \u00e9t\u00e9 d\u00e9couvert qu’en 1947 en onde radio et a alors re\u00e7u le nom de 3C 461. La contrepartie optique, tr\u00e8s faible, n’a, elle, \u00e9t\u00e9 d\u00e9couverte qu’en 1950. je l’ai imag\u00e9e depuis La Fosse avec la ST10XME plac\u00e9e au foyer r\u00e9duit du C11 (F=1785mm) en mode L(Ha)RVB sur plusieurs nuits de ce mois d’aout avec un temps de pose cumul\u00e9 de 14hrs 40 puis trait\u00e9e avec Pixinsight. L’image a \u00e9t\u00e9 recadr\u00e9e pour la publication.<\/p>\n
