Bonjour tout le monde.
\nComme Alain, j’ai op\u00e9r\u00e9 mon 300D pour une meilleure sensibilit\u00e9 \u00e0 la lumi\u00e8re H-alpha.
\nIl est \u00e0 pr\u00e9sent muni d’un filtre IR-cut Baader.
\nCes premi\u00e8res images-test sont des photos au sens traditionnel car une pose unique a \u00e9t\u00e9 faite pour chaque cible.
\nToutes \u00e0 400iso pour un bon S\/N. Lune au premier quartier.
\nAucun pr\u00e9traitement appliqu\u00e9 (ni dark ni offset), pas de compositage dans Iris etc.
\nJeu sur les courbes RVB, luminance et contraste. Gommage des pixels chauds \u00e0 la pipette.
\n-3min pour M13 et M57 au foyer du T255 de la SAL avec filtre Neodyme.
\n-4min de pose pour America au t\u00e9l\u00e9 200\/2.8 avec filtre rouge.
\nLe globulaire a visiblement b\u00e9n\u00e9fici\u00e9 d’un bon seeing.<\/p>\n
