On voit venir sur le march\u00e9 des nouveaux filtres destin\u00e9s au solaire.
\nBaader a renouvel\u00e9 son KLine (393nm) par un nouveau mod\u00e8le un peu plus \u00e9troit, 5nm de bande passante.
\nAntlia a sorti un 393nm avec 3nm de bande passante.<\/p>\n

Voici maintenant un filtre en bande G centr\u00e9 autour de 430nm, 2 nm de bande passante.
\nOn pourrait consid\u00e9rer ce filtre comme destin\u00e9 aux lunettes qui ont une perte de r\u00e9solution dans le proche UV.<\/p>\n

Voici deux images faites avec un newton solaire de 300mm d’ouverture et ce filtre Altair 430-2nm.<\/p>\n
