Bonjour \u00e0 toutes et \u00e0 tous,
\nJe vous pr\u00e9sente les photos de deux galaxies photographi\u00e9es depuis La Fosse avec le C11 \u00e0 F\/D 6.3 (1785 mm de focale), le 24 mars pour la crosse de hockey et le 27 mars pour le tournesol. La taille des images est r\u00e9duite \u00e0 75% de l’original pour le forum.<\/p>\n

NGC4656-4657 la galaxie de la crosse de hockey. Cette galaxie se trouve dans la constellation des Chiens de Chasse, \u00e0 environ 29 millions d\u2019ann\u00e9es-lumi\u00e8re de la Terre. Elle est en interaction avec la galaxie de la baleine (NGC4631 hors champ) ce qui a pour cons\u00e9quence de la d\u00e9former fortement. Le nuage d\u2019\u00e9toiles visible dans le haut de l\u2019image fait partie de la galaxie ; il a re\u00e7u son propre n\u00b0 NGC : 4657.<\/p>\n

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

M63 (NGC4826) la galaxie du tournesol est une belle galaxie spirale \u00e9galement situ\u00e9e dans la constellation des chiens de chasse, \u00e0 environ 22 millions d\u2019ann\u00e9es-lumi\u00e8re de la Terre mais certaines mesures non bas\u00e9es sur le redshift la situent \u00e0 25.2 millions d\u2019ann\u00e9es-lumi\u00e8re. Cette galaxie ferait partie du m\u00eame groupe de galaxies que M51. On peut remarquer un fin trait orang\u00e9 en bordure de M63, \u00e0 droite de son centre. Il s\u2019agit en fait d\u2019une galaxie lointaine d\u2019arri\u00e8re-plan : 2MFGC10580.<\/p>\n
