La nuit de ce mercredi 8 septembre 2004 \u00e9tait splendide…<\/p>\n

J’ai pu enfin mettre \u00e0 profit mon autoguidage webcam au service du Ha avec ce clich\u00e9 de la portion Ouest de la n\u00e9buleuse Veil dans le Cygne (NGC 6960). Il s’agit d’un compositage m\u00e9dian de 5 prises de 10 minutes chacune (!!!), ceci afin de minimiser l’impact du bruit de lecture de la cam\u00e9ra. Toutes les corrections y ont \u00e9t\u00e9 apport\u00e9es: bias, noir et plu. Prises de vue au foyer de la SKY 90 ouverte \u00e0 f5.6 \u00e0 l’aide de l’audine (KAF 401-E) \u00e9quip\u00e9e du filtre Ha d’Astronomik, le tout mont\u00e9 sur ma GP-DX.<\/p>\n

Le second clich\u00e9 est celui de la galaxie du Triangle M33 avec le m\u00eame \u00e9quipement mais sans Ha. Compositage m\u00e9dian de 20 poses de 2 minutes avec correction de bias, noir et plu.<\/p>\n

Vivement ce soir…<\/p>\n
