About Tele Vue BMB0125 Bandmate Mars Type B 1.25in Filter
Traditionally, standard colored filters have been used to bring out detail on the planet's surface. The main drawback is the artificial color imposed on all planetary features.
Bandmate Mars Type-B Filters
The Bandmate Mars Type-B filter is a high efficiency, single band dielectric coating that achieves penetrating views of the Martian surface. The surface appearance is similar to that of the popular #21 filter. However, the Type-B features a broadband anti-reflection coating on one side and filter coating on the other that makes it far more efficient.
