Description

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.

Features

• Optical grade BK7 glass to insure no image degradation due to the substrate.
• Ion beam deposition of the coatings produces hard, stable coatings to reduce changes due to temperature and humidity.
• Dielectric filter for high transmission and blocking of unwanted wavelengths provide high contrast images.
• Aluminum filter cells precision machined and engraved.

Description

Tele Vue offers two contrast enhancing filters specifically designed for viewing Mars, but also quite useful on Jupiter. 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. Bandmate™ Mars Type-A FiltersWe 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. Features of Tele Vue Bandmate™ Filters Optical grade BK7 glass to insure no image degradation due to the substrate. Ion beam deposition of the coatings produces hard, stable coatings to reduce changes due to temperature and humidity. Dielectric filter for high transmission and blocking of unwanted wavelengths provide high contrast images. Aluminum filter cells precision machined and laser etched.
