Celestron 1.25" Eyepiece Filter Set


Celestron 1.25" Eyepiece Filter Set (#21, #80A, #15 & Polarizing filters)

Celestron color filters are mounted in black anodized aluminum cells with the Kodak Wratten series number individually engraved. and come available in 4 assorted kits packed in plastic cases.  The cells of each filter are double-threaded, so they can be stacked (piggybacked) in various combinations.  This allows you to create different color combinations and transmission characteristics, or to have the same color characteristic, but with a lower transmission.  When stacking color filters, the effective transmission of the combination you create is equal to the product of the spectral transmission of each of the filters used.

Eyepiece filters are an invaluable aid in lunar and planetory observing.  They reduced glare and light scattering, increase contrast through selective filtration, increate definition and resolution, reduced irradiation and lessen eye fatigue.  Celestron's filters are made of high quality solid plane parallel glas with excellent homogeneity.  They are anti-reflection coated to prevent glaring and ghosting.  All eyepiece filters are threaded to fit Celestron's, and most other manufacturer's 1.25" eyepieces , and offer a full 26mm clear aperture.
