Blue filters above all make the details of the atmospheres of Jupiter and Saturn more visible, as well as those of the surface of Mars.
Dark blue is excellent for detecting cloud bands and the Great Red Spot (GRS) on Jupiter.
Red filters increase contrast with the Moon and reveal the polar caps on Mars. Dark red filters should only be used on larger telescopes.
Light red gives a strong increase in contrast with the Moon, as well as allowing easier observing of Mercury and Venus at dusk.
Violet filters are used for observing Venus (cloud structures) and increase contrast with Saturn’s rings.
Green filters enhance the contrast of surface details on the Moon, as well as details in the cloud structures of Jupiter (GRS) and Saturn (bands).
Light green also allows better observing of the ice caps on Mars.
Yellow filters suppress colour fringing with achromatic refractors and can be used as universal contrast filters for various objects in our solar system.
Yellow-green filters allow atmospheric details on Jupiter and Saturn to be detected more easily, even in smaller telescopes.
Yellow-orange filters increase contrast when observing Mars.
