Celestron Filter Set #3
Celestron offers four convenient filter sets, which contain four different filters per set. Not only are these highly useful filter combinations, but they also offer an economical way to add versatility to your filter collection.
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.
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.
All observing information for this filter is the same as that given for the #56 Green filter, with the exception of the following: Saturn Enhances white features in the Saturnian atmosphere. Comets Useful for observing brighter comets.
Moon Excellent for reducing irradiation, glare and subject brightness. Colors are unaltered, as light is transmitted uniformly over the entire spectrum. Each model performs somewhat differently, depending on the brightness of the moon. Planets Stacking in combination with color filters lowers transmission, but retains true color balance for specific applications. Reduces glare on brighter planets and minimizes irradiation. Binary Stars Helpful in splitting binary stars, because it reduces glare and diffraction effects around the brighter star of the binary pair.
