Details

This #56 light green Sirius-Optics 1.25" eyepiece filter can be used to good effect when observing a variety of features on every planet from Venus to Saturn with telescopes from 60mm to 150mm (6") in aperture . . .

Recommended applications for this filter:
Moon - Useful for enhancing the contrast of lunar features in scopes 6" and smaller. Venus - Useful for Venusian cloud pattern studies and to reduce the brightness of the terrestrial sky during daylight observing of Venus (an excellent time to observe this planet, as the high contrast of Venus against the dark night sky often makes for uncomfortable and unsatisfactory observing, while during the day the contrast range is not nearly as great, irradiation within your eye is reduced, and subtle Venusian features are sometimes more visible). Mars - Excellent for increasing contrast of Martian polar caps and surface frosts with scopes 6" and smaller. Jupiter - Increases the visibility of the Great Red Spot (which is more like a Faint Red Spot at the present time) with scopes 6" and smaller. Useful for observing the low-contrast hues of red and blue visible in the Jovian atmosphere. Enhances white features in the planetary atmosphere. Saturn - Enhances white features in the planetary atmosphere.
