Salut \u00e0 tous,<\/p>\n

Je vous pr\u00e9sente quelques r\u00e9sultats obtenus au Val d’Aoste en Italie \u00e0 1800m d’altitude au cours de deux nuits douces et transparentes (le 26 et 27 juin 2005). <\/p>\n

Tous les clich\u00e9s sont pris au foyer de la TAKAHASHI FSQ-106N ouverte \u00e0 f5 avec un APN Canon 300D, le tout mont\u00e9 sur une monture GP-DX sans autoguidage. Le premier essai concerne la n\u00e9buleuse Trifide M20 qui r\u00e9sulte d’un compositage m\u00e9dian de 12 poses de 2 minutes apr\u00e8s correction du noir et de l’\u00e9quilibre chromatique (en utilisant les poids propos\u00e9s par C. Buil). <\/p>\n

Les deux photos qui suivent (les n\u00e9buleuses du Lagon M8 et la North America NGC 7000) sont le r\u00e9sultat d’un compositage m\u00e9dian de 10 poses de 3 minutes avec les m\u00eames corrections de base. La lune commen\u00e7ait d\u00e9j\u00e0 \u00e0 se lever au moment de la prise de vue. Il appara\u00eet clairement sur ces deux exemples la difficult\u00e9 d’\u00e9quilibrer le rendu des couleurs \u00e0 partir d’un capteur relativement peu sensible \u00e0 la raie Ha. Il faudra donc que je l’op\u00e8re si je veux en optimiser l’utilisation an astrophoto de ciel profond.<\/p>\n

A bient\u00f4t,<\/p>\n
