TeleVue Bandmate Type A Mars Filter - 1.25"
Tele Vue is pleased to announce two new contrast enhancing filters specifically designed for viewing the planet Mars. Why two filters? 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.
We all know you can’t have your cake and eat it too, but the Bandmate™ Mars Type-A lets you at least have a good taste! The Type-A is a dual-band filter with different dielectric coatings on each side of the substrate. The dual band nature of the filter permits green and red to pass through while rejecting all other visible colors. The effect is to enhance detail on the Martian surface while preserving the natural color of the polar caps and rest of the surface. Since this filter provides a most natural view, it is highly recommended for public viewing.
