All of the planetary filters included\nin the Celestron lunar and planetary filter set can be used on any 1.25”\neyepiece with the proper filter threads, so they are very versatile. Just\nscrew one onto the eyepiece of choice and slide it into the focuser.This\nCelestron filter set includes the following colors: 12 deep yellow - A good\ngeneral purpose filter for smaller aperture telescopes (less than 4.5”), The\n12 Yellow will improve the contrast of features on the Moon. It will also\nhelp you see the equatorial belts on Jupiter and Saturn, clouds and the Polar\nice caps on Mars, and the dusky detail on Uranus and Neptune. 21 orange -\nsharpens the boundaries along the plains of Mars due to the reduction of\nblue\/green transmissions. Use on Jupiter and Saturn to enhance detail in the\nbelts and Polar regions. 80A Blue - enhances the contrast of the Cloud belts\non Jupiter and the Polar ice caps on Saturn. It also can be used to increase\ncontrast on the Moon If you don’t mind the color shift. Including-96-03\nneutral Density - A great filter for the moon, and for stacking with other\nplanetary filters to increase Density without changing the color. A Neutral\nDensity filter is also useful when splitting binary Star systems (double\nstars). use anytime you want to decrease brightness but don’t want to affect\nthe color characteristics of an object. Each Celestron 1.25” filter has 26 mm\nof clear Aperture, and is mounted in a black anodized aluminum cell that is\nthreaded on both sides. Double threads allow the user to stack different\nfilters together to create a custom color or affect the transmission\npercentage. Special coatings on each filter protect against reflections,\nghosting, and scratches. A plastic case is included to keep your filters safe\nwhen not in use. Eyepiece filters are an invaluable aid in lunar and planetary\nobserving. They reduce glare and light scattering, increase contrast through\nselective filtration, increase definition and resolution, reduce irradiation\nand lessen eye fatigue. Celestron's filters are made of high quality, solid\nplane parallel glass with excellent homogeneity. They're anti-reflection\ncoated to prevent glaring and ghosting. All eyepiece filters are threaded to\nfit Celestron's, and most other manufacturer's, 1.25 inch eyepieces, and offer\na full 26 mm clear aperture. Celestron color filters are mounted in black\nanodized aluminum cells with the Kodak Wratten Series Number individually\nengraved, and come available in 4 assorted kits packed in plastic cases. The\ncells of each filter are double-threaded, so they can be stacked (piggybacked)\nin various combinations.This allows you to create different color combinations\nand transmission characteristics, or to have the same color characteristic,\nbut with a lower transmission. When stacking color filters, the effective\ntransmission of the combination you create is equal to the product of the\nspectral transmission of each of the filters used. The effectiveness of the\nfilters depends on several factors, including: the aperture and focal length\nof the telescope, the magnification being used, and seeing conditions.
