Bonjour,<\/p>\n

Voici ma premi\u00e8re photo CCD de M57 en couleur prise au foyer d’un Celestron 9,25″ (f\/10) sur une monture Vixen GP-DX et son Skysensor dans la nuit du 28 au 29 juillet sous abri \u00e0 Desni\u00e9. (Heure : +\/- 2h30 TL, temp\u00e9rature 19\u00b0, vent presque nul et ciel transparent sans brume).<\/p>\n

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

LRGB de M57<\/p>\n

Mat\u00e9riel utilis\u00e9 : une cam\u00e9ra CCD Audine Kaf-0401 avec sa roue \u00e0 filtre SBIG nouvellement achet\u00e9.
\nAcquisition : 20 images (en bining 2×2) de 20sec dans chaque plan LRGB, suppression du dark moyenn\u00e9 de l’image brute, recalage en s\u00e9rie et addition par m\u00e9diane de la LRGB. Pas de masque flou. Temps de pause total : 6m40sec.<\/p>\n

Le r\u00e9sultat est satisfaisant malgr\u00e9 un suivi m\u00e9diocre de la monture… Pour un premier essai en couleur, je suis quand m\u00eame content mais des progr\u00e8s sont \u00e0 faire au niveau de la mise en station… et du suivi. <\/p>\n

Prochain essai lors d’une nuit claire et sans brume et bien s\u00fbr \u00e0 la NEF…<\/p>\n
