#8 Light Yellow
Recommended applications for this filter:
Moon – Improves contrast and reduces irradiation between lunar features of varying brilliance in scopes under 5", 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 – Darkens blue and green maria, oases, and canal markings while it lightens the orange-hued desert regions. 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. Saturn – Somewhat useful for darkening atmospheric currents containing low-hue blue tones. 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 enhances comet heads.

#21 Orange
Recommended applications for this filter:
Moon – Very useful for improving contrast between lunar features in scopes 6" and larger, with or without polarizer. Mercury – Darkens terrestrial sky during daylight viewing to enhance rarely visible subtle surface albedo differences. Venus – Darkens terrestrial sky during daylight viewing to show the phases more clearly. 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 – Brings out structure in the belts and enhances festoons and polar regions. Saturn – Improves the structure of atmospheric bands and highlights blue-toned polar regions. Comets – Can be piggybacked with #38A filter to improve contrast of orange Sodium D lines in comet gas tails in scopes 10" and larger. Enhances the definition of comet heads and dust tails in 10" and larger scopes. Solar – Used to give correct color rendition of the Sun when using a Mylar solar filter.

#38A Dark Blue
Recommended applications for this filter:
Moon – Somewhat useful for improving contrast between lunar features in scopes 8" 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 – Enhances low-contrast features between the belts and zones in the planetary disc. Comets – Brings out the best definition in comet gas tails. Useful with 10" and larger scopes for observing orange Sodium D lines in gas tails when combined with #21 filter.

#56 Light Green
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.
