Par ces temps maussades, je suppose que vous n’en avez pas marre de voir le soleil…
\nNouveaux essais ce matin entre les nuages.
\nLe fait que la lunette soit achro et non pas apochromatique ne semble pas p\u00e9nalisant avec l’usage du filtre continuum 540 nm, + filtre de Hershell Baader et un filtre neutre densit\u00e9 1.8. Temps d’exposition en \u00b5Sec : 273.
\nChaque image est le r\u00e9sultat du stack sous Autostakkert2 de 100 images issues d’un film de 1 minute.
\nOn voit bien la granulation.
\nLa Terre est \u00e0 l’\u00e9chelle.
\nEffectivement, un grain fait \u00e0 peu pr\u00e8s 1000 km compar\u00e9 au diam\u00e8tre terrestre.
\nLa qualit\u00e9 est meilleure par rapport aux essais pr\u00e9c\u00e9dents.
\nC’est probablement li\u00e9 \u00e0 la moindre turbulence du matin.<\/p>\n
