Il y a tr\u00e8s longtemps que je m’\u00e9tais promis de refaire une photographie de M13, le plus brillant amas globulaire de l’h\u00e9misph\u00e8re nord. Voil\u00e0 qui est fait … 8 ans apr\u00e8s ma derni\u00e8re image ! Je peux ainsi constater les progr\u00e8s op\u00e9r\u00e9s.

Le script d’Astrom\u00e9trie de Pixinsight permet de r\u00e9p\u00e9rer les galaxies pr\u00e9sentes sur l’image, on observe les deux en jaune qui sont bien visibles, mais \u00e9galement tous les cercles bleus qui montrent la position de galaxies r\u00e9f\u00e9renc\u00e9es dans le catalogue PGC.<\/span><\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

M13 \u00e9tait un objet id\u00e9al, en ce mois d’ao\u00fbt 2011, pour faire mes premiers pas en autoguidage. J’ai fait l’acquisition de 20 poses de 3 minutes que j’ai toutes conserv\u00e9es pour faire l’image finale, le syst\u00e8me semble donc bien fonctionner. J’ai laiss\u00e9 l’image en grand champ afin qu’on voit les deux galaxies qui sont pr\u00e9sentes. La premi\u00e8re est \u00e9vidente mais voyez-vous la deuxi\u00e8me ?<\/span><\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
