Bandmate filters yield bright, sharp and contrasty images - even in the optically sensitive position in front of the diagonal. Optical glass and red filtering allows for sharp and bright views of nebulae with embedded star clusters - such as the Lagoon Nebula (M8).

Bandmate 1.25" Mars Type-B Filter
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.
