Mars & Planetary Filters

Tele Vue offers contrast enhancing filters specifically designed for viewing Mars, Jupiter and Saturn. Why multiple 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. These complex filter designs are made possible by Ion Beam Sputtering (IBS) technology.
We all know you can't have your cake and eat it too, but the Bandmate™ Mars Type-A filter 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 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.
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.
Maintains the exceptional contrast of the Type-A with a more neutral color balance that particularly enhances viewing Jupiter and Saturn.
