You may not see little green guys with antennae, but you will resolve plenty of subtle features with this Orion Mars-optimized telescope filter set. It consists of three 1.25" glass filters in threaded aluminum cells:

1. The custom-designed Orion 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.
2. The Blue #82A filter really "pops" the polar icecaps and nicely highlights polar hoods and clouds.
3. The Orange #21 filter sharpens visibility of dark surface markings and polar regions. Surface dust storms become easily visible.
4. Set includes 3-filter case.
