Filters

Increase your contrast using filters

Below you will find a complete overview of all available filters and their various functions. Filters make sure contrasts are observed with more clarity. What’s more, a great number of observations can only be done in this way!

When you are going to observe Mars, for example, you can use a yellow filter in order to get a good view of the clouds. For the polar caps you use a green filter, and so on and so forth.
Please find the manual below.

Polar filter (nr. 3)

For increasing contrast between lunar features of varying brightness.
Increases contrast between surfaces of varying planetary transmissions
Enriches blue heavens with a deeper shade of blue.
Removes surface reflections
Reduces atmospheric haze.

Yellow filter (nr. 12)

Moon: for increasing contrasts between lunar characteristics under various light conditions.
Venus: to be able to view the contrast of the thick Venus cloud under good light conditions.
Mars: for increasing contrast of the polar caps, frozen areas and low-hanging clouds.
Jupiter: for darkening atmospheric currents.

Orange filter (nr. 21)

Moon: for increasing contrasts in the lunar landscape
Mercury: to reduce the brightness of the observation during daytime observations.
Venus: to reduce the brightness of the observation during daytime observations.
Mars: to improve contrast of the polar caps, frost areas and low-hanging clouds
Jupiter: to be better able to observe the belt structure.
Saturn: to have a better look at the atmospheric bands.

Red filter (nr. 23A)

Moon: (somewhat useful) for increasing contrast of lunar features.
Mercury: to improve observations when Mercury is in the twilight zone (when the planet is close to the horizon).
Venus: to reduce brightness when observing during the daytime.
Mars: to improve contrast of the polar caps, frost areas and ochre deserts.
Jupiter: (very useful) to be able to observe blue-tinted cloud formations.
Saturn: to be able to establish the blue-tinted cloud formations.

Green filter (nr. 56)

Moon: to increase contrast between lunar features in various light conditions.
Venus: to view the cloud patterns.
Mars: to increase contrast of the polar caps and to be able to observe frost.
Jupiter: to enhance visibility of the big red spot.
Saturn: to be better able to observe the white elements in the atmosphere.

Light blue filter (nr. 82A)

Moon: to increase contrast between lunar surfaces.
Jupiter: enhances the boundaries between the red belts and the adjacent bright zones.
Mars: useful during violet clearing and when studying surface characteristics of polar caps.
Saturn: improves low contrast details of cloud formations.

Light yellow filter (nr. 8)

Moon: to improve contrast and to reduce irradiation between lunar characteristics (suitable for telescopes under 127mm).
Venus: (slightly useful) for revealing low-contrast banding in Venus’s thick clouds.
Mars: to darken blue and green maria, oases and channel demarcation. In addition, orange desert areas are highlighted.
Jupiter: (somewhat useful) for darkening currents in blue tints and improving details in small orange-red features in the belts.
Saturn: (slightly useful) for darkening currents containing low-blue tones
Neptune and Uranus: (somewhat useful) for improving very subtle dark features (suitable for telescopes of 250mm and bigger).
Comets: to bring out highlights in yellowish comet dust tails and to improve the contrast of comets.

Yellow-green filter (nr. 11)

Moon: to increase contrast between lunar features (suitable for telescopes under 127mm)
Mars: to increase the contrast of polar icecaps, frost areas, low-hanging clouds and dust storms in the deserts. This filter also highlights boundaries of yellow dust storms.
Saturn and Jupiter: contrasts blue and red features.
Neptune and Uranus: (slightly useful) for improving very subtle dusky features (for scopes of 250mm and bigger).
Comets: to bring highlights in yellowish comet dust tails to the fore and to improve the contrast of comet heads.
78% transmission

Violet filter (nr. 47)

Mercury: (somewhat useful) for improving observations of rarely visible vague surface features (suitable for scopes of 200mm and bigger).
Venus: to improve contrast of faint dark shadows of the upper cloud sheet.
Mars: to detect high clouds and mist above the polar icecaps (suitable for telescopes of 200mm and bigger).
Jupiter: to enhance boundaries between the reddish belts and the adjacent bright zones in the upper atmosphere.
Saturn: to enhance the ring structure (for telescopes of 200mm and bigger)
Comets: for observing brighter comets (suitable for telescopes of 200mm and bigger).
3% transmission

Moon filter Crystal view

This filter enhances the contrast of the lunar surface and blocks out superfluous light.
