Comme les conditions m\u00e9t\u00e9o se d\u00e9gradent pour au moins 15 jours, je me suis dit qu’il fallait profiter de la petite \u00e9claircie (qui n’a pas dur\u00e9 tr\u00e8s longtemps) en soir\u00e9e.
\nCapture de la plan\u00e8te g\u00e9ante Jupiter avec son bel anticyclone appel\u00e9 la Grande Tache rouge de la grandeur de la Terre et, \u00e0 gauche, un de ses principaux satellites nomm\u00e9 Io – le volcanique (objet le plus g\u00e9ologiquement actif de tout le syst\u00e8me solaire).<\/p>\n

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

Caract\u00e9ristiques de prises de vue:
\n. 8 vid\u00e9os de 90 sec \u00e0 230 de gain et une exposition de 24ms
\n. Assemblage des 8 vid\u00e9os dans le logiciel AutoStakkert o\u00f9 il n’a \u00e9t\u00e9 gard\u00e9 que 12% des meilleures images.
\n. Passage dans le logiciel AstroSurface pour am\u00e9liorer les d\u00e9tails, contraste, etc
\n. Comme la plan\u00e8te tourne tr\u00e8s vite sur elle-m\u00eame (une dizaine d’heures), on va faire subir une d\u00e9rotation aux 8 images obtenues et empiler les images pour am\u00e9liorer le rapport signal\/bruit – ceci est rendu possible gr\u00e2ce au logiciel Winjupos.<\/p>\n

Au-del\u00e0 de ces consid\u00e9rations techniques, n’h\u00e9sitez pas \u00e0 regarder plein sud, m\u00eame s’il n’y a qu’une petite \u00e9claircie et vous ne manquerez pas d’apercevoir la plan\u00e8te g\u00e9ante bien brillante dans le ciel. Munissez-vous d’une simple paire de jumelles et admirez le petit disque de la g\u00e9ante ainsi que ses 4 satellites …<\/p>\n
