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

Je vous pr\u00e9sente deux clich\u00e9s reprenant des classiques d’hiver, \u00e0 savoir la n\u00e9buleuse de La Rosette dans la Licorne et la T\u00eate de Cheval dans Orion. Ils ont \u00e9t\u00e9 pris ce lundi 23 janvier 2006 \u00e0 Harz\u00e9 dans des conditions de seeing tr\u00e8s m\u00e9diocres en grande partie li\u00e9es \u00e0 un vent assez fort.<\/p>\n

L’APN Canon 300D modifi\u00e9 se trouvait au foyer Newton du CN212 ouvert \u00e0 f4. L’autoguidage a \u00e9t\u00e9 assur\u00e9 par une petite cam\u00e9ra de surveillance \u00e9quip\u00e9 du Sony ExView qui permet de s’accrocher \u00e0 des \u00e9toiles de magnitude fr\u00f4lant 10 au foyer de la BORG76 de 500mm de focale. Le lien avec le PC utilise un convertisseur \u00ab\u00a0Video Grabber\u00a0\u00bb qui transmet l’image au logiciel AstroArt pour la fonction d’autoguidage.<\/p>\n

Dans le cas de la T\u00eate de Cheval, 7 clich\u00e9s de 5 minutes ont subi un compositage m\u00e9dian, alors que pour La Rosette, il s’agit d’un compositage de 14 prises de 5 minutes. La correction noir et PLU ont \u00e9t\u00e9 appliqu\u00e9s.<\/p>\n
