Celestron Telescope Polarizing Filter Set - 1-1/4" 93608 Product Info

Celestron Polarizing Filter Set for 1-1/4" Eyepieces

Item #93608 :

Ambient daylight is normally comprised of multiple wavelengths of light, vibrating in multiple planes. Celestron Eyepiece Polarizing Filter Set-93608 transmits only light moving along a specific plane, thereby increasing the contrast between surfaces with different planar transmissions. Generally, the polarization effect makes blue skies a deeper blue, eliminates surface reflections and helps reduce atmospheric haze.

Celestron Telescope Polarizing Filter Set 93608 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 color of the object being observed. Filter Set is comprised 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, Celestron Polarizing Filters Set transmits only 5% of entering light.

Package Contents:

• Celestron Telescope Polarizing Filter Set 1.25":

  - two filters;

  - filter adapter.

Wynika, że od 5 do 30%. Szkoda, filtr Oriona przepuszcza od 1 do 40% a ja szukam czegoś w tym zakresie . Ale cena jest ok.
