Orange

#8 Yellow 83% T [Series 4]

All observing information for this filter is the same as that given for the #12 and #15 Deep Yellow filters, with the exception of the following:

Mars – Improves the Martian maria by reducing scattered light from blue areas, while allowing passage of more green light for studying yellow dust clouds. Comets – Brings out highlights in yellowish dust tails and enhances appearance of comet heads.

#21 Orange 46% T [#94118-05 & Series 1]

Moon – Greatly enhances lunar features. Jupiter – Improves appearance and detail revealed in structure of Jovian belts. Enhances viewing of festoons and polar regions. Mars – Reduces light from the blue and green areas which darken the maria, oases and canal markings, while lightening the orange-hued desert regions. Also sharpens the boundaries of yellow dust clouds. Mercury – Reduces the brightness of blue sky during daylight observing, to reveal surface features. Saturn – Improves structure of the Saturnian bands and highlights blue polar regions. Venus – Use during daylight observing to reduce brightness of blue sky. Comets – Enhances definition of comet dust tails and heads in larger telescopes (11" and greater aperture). Solar – When using a Celestron Mylar Solar Filter, adding this orange filter will give true color rendition.

RED

#25 Red 14% T [#94118-07 & Series 2]

Moon – Improves lunar features. Jupiter – Useful for studying bluer clouds. Mars – Ideal for observation of the polar ice caps and features on the Martian surface. Sharpens the boundaries of yellow dust clouds. Mercury – Improves observation at twilight, when the planet is near the horizon. During daylight, it reduces the brightness of the blue sky to enhance surface features. Saturn – Useful for studying bluer clouds. Venus – Use during daylight observing to reduce

brightness of blue sky. Occasionally deformations of the terminator are visible.

#23A Light Red 25% T [Series 3]

All observing information for this filter is the same as that given for the #25 filter, with the exception of the following:

Mars – Reduces light from blue and green areas which darkens the maria, oases and canal markings, while lightening the orange-hued desert regions. Sharpens the boundaries of yellow dust clouds. Comets – Improves definition of comet dust tails.

BLUE

#80A Light Blue 30% T [#94118-12 & Series 1]

#82A Pale Blue 73% T [Series 4]

#38A Blue 17% T [Series 3]

Moon – Enhance lunar detail. Jupiter – Enhance the boundaries between the reddish belts and adjacent bright zones. Useful for viewing the Great Red Spot. Mars – Very useful during the violet clearing. Helpful in studying surface features and polar caps. Mercury – Improve observation of dusky surface markings at twilight, when the planet is near the horizon. Saturn – Enhance low-contrast features between the belts and zones. Venus – Useful for increased contrast of dark shadings in upper Venusian clouds. Comets – Bring out the best definition in comet gas tails.
