Description du produit
Le filtre à bande étroite 2" OIII isole uniquement les deux lignes d'oxygène doublement ionisées (lignes 496 et 501 nm) émises par les nébuleuses planétaires et d'émission, tout en bloquant le reste du spectre global de la lumière. Le résultat est un contraste extrême entre le fond de ciel noir et les photons faibles de la lumière OIII nécessaires pour des vues détaillées des nébuleuses du voile, de l'anneau, de l'haltère, du croissant et d'Orion, entre autres objets.
Chaque filtre a un revêtement ultra dur déposé sous vide soigneusement conçu pour bloquer tout le spectre visuel allant de 400 à 700 nm. Cela élimine les halos colorés non naturels entourant les étoiles brillantes communes avec les filtres O III de technologie de revêtement moins sophistiquée.
