Description du produit
Filtre solaire à double pile LS40FHa
Le filtre solaire Lunt LS40FHa est un étalon intégralement réglé à ouverture de 40 mm (sans obstruction centrale) pour une utilisation sur les télescopes Lunt dédiés de 40 mm.
L'unité à double pile Lunt LS40FHa est destinée à être utilisée avec le système Alpha dédié à l'hydrogène Lunt 40 mm et nécessite un filtre de blocage des systèmes solaires Lunt (il s'agit d'une exigence de sécurité).
Étant donné que le filtre solaire LS40FHa a une bande passante estimée <0,70 Angström, il est capable de fournir des vues à contraste élevé des détails de la surface et des bords. De manière significative, l’ajout d’un système étalon supplémentaire (double empilement) réduira la bande passante à ~<0,50. Permet une visualisation et/ou une imagerie à plus haute résolution.

Customer Reviews
Used this to double stack behind my quark and it now means i have a 102mm double stacked h-alpha scope for less than $2000. It just doesn’t get better than that except for the scope still works for calcium and white light in seconds. Shipping was very fast.
