• Unique set of high-performance observational filters markedly improve views of Mars through your telescope
• Fully-coated Mars filter increases contrast to bring out subtle detail, even in smaller telescopes.

The custom-designed Mars Observation filter enhances contrast of virtually all surface features. Dielectric coatings transmit violet/blue (<505nm) and orange/red (>615nm) wavelengths where detail is rich, while blocking overbearing yellow/green (515nm-615nm) wavelengths. Polar icecaps appear more sharply defined, and differences in landscape shading are nicely resolved. Polar hazes and cloud cover become visible. The filter's high transmission makes it effective even in small telescopes. Custom-engineered filter comes with protective plastic case.
