Comme d\u00e9j\u00e0 mentionn\u00e9, le T250 solaire est con\u00e7u pour laisser passer le spectre bleu profond.
\nJ’aime beaucoup le filtre K-Line \u00e0 ~390nm. Les images sont tr\u00e8s contrast\u00e9es et les facules ressortent bien, m\u00eame si la longueur d’onde est plus contraignante.<\/p>\n

AR2674 est un groupe de 2 taches en fait. Ici, une mosa\u00efque; l’approche du bord se fait ressentir:<\/p>\n
