Polarizing Filterset Ref: DH-93608

CELESTRON

The Polarizing Filter Set is intended for visual use. It`s particularly useful for reducing glare while observing the moon, double stars, the planets and terrestrial subjects, all without affecting the colour of the object being observed.

The Filter Set is made up of two filters that thread into either the eyepiece or the filter adapter, which comes with the set. When one filter is used alone, you get 30% light transmission. When both filters are used together, you can vary the degree of transmission. By causing the amount of transmitted light to vary, the filters become, in effect, a continuously variable neutral density filter. At maximum density, the Polarizing Filter Set transmits only 5% of the light.
