Bonjour.<\/p>\n

Pas d’aurores mais une activit\u00e9 solaire qui reste intense !
\nVoi\u00e7i des images du 05\/10.
\nImages en H-alpha c’est-\u00e0-dire dans le rouge centr\u00e9es sur la raie de l’hydrog\u00e8ne \u00e0 656.3 nm.
\nGrace une double filtration H-alpha le globe devient cotonneux avec une limite lin\u00e9aire du limbe qui dispara\u00eet.
\nOn ne voit pas la photosph\u00e8re sous-jacente, on voit la chromosph\u00e8re.
\nOn a plus l’impression de relief.
\nBeaucoup d’activit\u00e9 avec toutes ces taches, des filaments aux formes vari\u00e9es, des protub\u00e9rances, des zones sur-brillantes \u00e9ruptives,
\ndes spicules qui donnent un aspect buissonnant…
\nLa terre est repr\u00e9sent\u00e9e \u00e0 l’\u00e9chelle.
\nUne grille d’orientation du soleil est associ\u00e9e.
\nLa mise au point n’est pas bonne sur tout le champ.
\nSans doute li\u00e9 au fort tilt n\u00e9cessaire pour faire dispara\u00eetre les Newton rings. <\/p>\n

Marc. <\/p>\n

\nCam\u00e9ra Asi 1600, c’est sans doute sur-\u00e9chantillonn\u00e9 mais j’aime son grand champ…
