Product Description

This Meade color filter set of four 26mm clear aperture 1.25" filters is pre-packaged at a savings over the total cost of the same filters bought individually. This set #1 is generally the most useful with 8" and larger scopes, as it has the filters most often used when observing the Moon, Mars, Jupiter, and Saturn. The set consists of one each of the following filters:

#12 Yellow
Recommended applications for this filter:
Moon - Improves contrast between lunar features of varying brilliance in scopes 6" and larger, especially when combined with a polarizer or neutral density filter. Venus - Occasionally helpful in revealing low-contrast banding in the thick Venusian cloud cover. Mars - Increases the contrast of polar caps, frost areas, low clouds, and dust storms against the ochre deserts. Also sharpens the boundaries of yellow dust clouds. Jupiter - Somewhat useful for darkening atmospheric currents containing low-hue blue tones and enhancing detail in small orange-red zonal features in the belts. Useful for studies of the polar regions. Saturn - Somewhat useful for darkening atmospheric currents containing low-hue blue tones and enhancing detail in orange-red zonal features in the belts. Improves the visibility of Cassini's Division in the rings. Neptune and Uranus - Somewhat useful for enhancing very subtle dusky features in scopes 10" and larger. Comets - Brings out highlights in yellowish comet dust tails and improves the contrast of comet heads.

#23A Light Red
Recommended applications for this filter:
Moon - Somewhat useful for improving contrast between lunar features in scopes 8" and larger. Mercury - Improves observations at twilight, when the planet is near the horizon. Reduces brightness of terrestrial sky to enhance daylight observing. Venus - Reduces brightness of terrestrial sky in daylight observing, allowing occasional terminator deformations to be seen. Mars - Filters out scattered blue light in the Martian atmosphere to Increase the contrast and definition of polar caps, frost areas, low clouds, and dust storms against the ochre deserts, particularly when Mars is close to Earth's horizon, as the red light it passes is the least refracted by air currents in our atmosphere. Jupiter - Brings out structure in the belts and enhances festoons and polar regions. Saturn - Useful on Saturn for studying the bluer cloud bands and polar regions. Comets - Enhances the definition of comet dust tails in 10" and larger scopes.

#58 Green
Recommended applications for this filter:
Moon - Excellent for enhancing the contrast of lunar features in scopes 8" and larger. Venus - Increases contrast of occasionally-visible Venusian cloud patterns. Reduces 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 8" and larger. Jupiter - Increases the visibility of the Great Red Spot (which is more like a Faint Red Spot at the present time) with scopes 8" and larger. 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 cloud belts and polar regions. Comets - Useful for observing brighter comets with scopes 8" and larger.

#80A Medium Blue
Recommended applications for this filter:
Moon - Very useful as a contrast-enhancing lunar filter under dark sky conditions with scopes 6" and larger. Mercury - May improve observations of rarely visible dusky surface features at twilight, when the planet is near the horizon. Venus - Increases contrast of occasional faint dark shadings in upper Venusian clouds. Mars - Useful for enhancing the visibility of surface features and localized dust storms, clouds, and ice fogs with 8" or larger scopes, particularly during the still-unexplained phenomenon of violet clearing (when the Martian atmosphere - normally a bright, featureless disc in violet light due to the scattering of short wavelengths of light by the thin atmosphere - becomes transparent through a violet or blue filter, revealing large dark surface features). Jupiter - Primarily used for enhancing the boundaries between the reddish belts and adjacent bright zones in the upper atmosphere. Helpful in defining the Great Red Spot and festoons in the belts. Saturn - Brings out details in the belts, zones, and polar regions of the planetary disc. Comets - Brings out the best highlight definition in comet gas tails in 8" and larger scopes.
