Eyepiece filters are an invaluable aid in lunar and planetary observing. They reduce glare and light scattering, increase contrast through selective filtration, increase definition and resolution, reduce irradiation and lessen eye fatigue.

This filter strongly increases the contrast of Mars’ polar ice caps, and increases contrast of atmospheric phenomena on Venus.
