Le 4 octobre avait lieu l’opposition de Saturne, c’est-\u00e0-dire que la plan\u00e8te aux anneaux, la n\u00f4tre et le Soleil sont align\u00e9s. Cela correspond aussi \u00e0 la plus petite distance entre Saturne et nous.<\/div>\n<\/div>\n
\n
Voici une photo de la belle avec un de ses satellites appel\u00e9 Rh\u00e9a.<\/div>\n<\/div>\n
\n
Puis vient l’animation d’une heure et montre le d\u00e9placement de ce satellite ainsi que les \u00ab\u00a0spokes\u00a0\u00bb dans les anneaux. Ces formations sombres sont des temp\u00eates de poussi\u00e8res microscopiques caus\u00e9es par l’interaction entre le vent solaire et le champ magn\u00e9tique de Saturne…<\/div>\n<\/div>\n

\nT\u00e9lescope de 280mm de diam\u00e8tre, lentille de Barlow 2.5X, ADC<\/em>
\nPour la photo, j’ai utilis\u00e9 Sharpcap et son livestack qui fonctionne souvent tr\u00e8s bien.<\/em>
\nPour l’animation, j’ai fait 18 vid\u00e9os de 180s avec FireCapture de 1h45 \u00e0 2h45. J’ai ensuite utilis\u00e9 Autostakkert avec 20% des meilleures images.<\/em>
\nIl y avait une brume tr\u00e8s tr\u00e8s l\u00e9g\u00e8re qui a peut-\u00eatre aid\u00e9 \u00e0 la stabilit\u00e9 des images.<\/em><\/div>\n<\/div>\n\n\n
