Voici un essai solaire en Ha, le double stack.<\/p>\n

D\u2019abord une image faite avec un Daystar 0.5A. C’est ma premi\u00e8re session avec ce filtre, et je n’ai pas encore cherch\u00e9 sa bonne temp\u00e9rature de travail.<\/p>\n

\"\"<\/a><\/p>\n

Ensuite, une image faite au Solar Spectrum 0.3A. Les conditions de seeing au moment de la capture \u00e9taient meilleures.<\/p>\n

\"\"<\/a><\/p>\n

Finalement, une image en double stack.
\nJ’ai \u00e9t\u00e9 fort surpris pas le temps d’exposition, qui a \u00e9t\u00e9 multipli\u00e9 par ~20, et l\u00e0 dessus j’ai du augmenter le gain.
\nL’image \u00e9tait plus contrast\u00e9e, mais au vu des param\u00e8tres de capture, le bruit pr\u00e9sent et la finesse perdue.
\nLe r\u00e9sultat est d\u00e9cevant.
\nStacker 2 \u00e9talons en mica n’est visiblement pas le bon plan.<\/p>\n
