Bonjour.
\nLes images de ce jours sont prises avec un PST modifi\u00e9.
\nOn voit bien l’ombre et la p\u00e9nombre des tache, les fibrilles,
\ndes facules, des filaments et protub\u00e9rances. <\/p>\n

Techniquement, ce n’est pas la qualit\u00e9 d’un solar spectrum mais il y a quand m\u00eame du signal H-alpha.
\nLe budget n’est \u00e9videmment pas le m\u00eame.
\nLe Fabry Perot du PST est con\u00e7u pour fonctionner \u00e0 F10.
\nIl s’enl\u00e8ve assez facilement, mais il faut forcer un peu pour le d\u00e9visser.
\nIl y a une lentille x 3 avant pour monter \u00e0 F30.
\nUne lentille arri\u00e8re ram\u00e8ne \u00e0 F10.
\nCes lentilles sont enlev\u00e9es assez facilement.
\nIl faut utiliser un ERF devant la lunette.
\nDerri\u00e8re le Fabry Perot il faut utiliser un BF, i\u00e7i un BF 15.<\/p>\n
