Meade - SET #1 Color Filter Series 4000

# 12 Yellow (74% transmission): Contrasts strongly with blue-colored features on Jupiter and Saturn, while enhancing red
and orange features. Lightens red-orange features on Mars, while reducing or blocking the transmission, and thereby increasing the
contrast, of blue-green areas. Useful in increasing the contrast of lunar features in telescopes 6" aperture and larger.

# 23A Light Red (25% transmission): On telescopes of 6" aperture and larger the # 23A does approximately the same
functions as the # 21 filter, but with stronger contrast and enhancement of marginally defined blue-green surface detail. Useful
primarily on Jupiter, Saturn, and Mars. Increases contrast between Mercury and bright blue sky during daylight observations or
during twilight.

# 58 Green (24% transmission): Use on telescopes 8" aperture and larger to reject blue- and red-toned structures on the
surface of Jupiter and thereby increase their contrast relative to lighter parts of the disc. Also use for the enhancement of
Saturn's cloud belts and polar regions. Strongly increases contrast of Mars' polar ice caps, and increases contrast of atmospheric
phenomena on Venus.

# 80A Blue (30% transmission): A popular filter for the study of Jupiter and Saturn. Enhances contrast of rilles and
festoons in Jupiter's cloud belts, as well as details of the Red Spot. Brings out detail in Saturn's belts and polar phenomena.
Very useful as a contrast-enhancing lunar filter.
