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-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 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.
