Variable 1,25-inch Steles Head Filter Made of Optical Glass with Linear PolarizationCPL Filter for Astrological Telescopes to Improve Moon and Star View
First-class materials and workmanship: This CPL filter consists of an anodized aluminum frame, is precision-grinded and highly glossy polished to ensure a long service life.
Improved contrast: The use of two -part optical glass is reduced by the light quantity entering in the eyepiece, thereby increasing the contrast of the eyepiece. If you look at bright objects such as the moon or certain planets, you can gradually reduce the field of to a measure that increases the contrast and increases the amount of visible details.
Reduced: The polarization filter reduces by leaving only 13 % of the reflected light through, which means that you can see the moon more clearly and study the moon more comfortably.
Simple application: The polarization filter has a standard M28.5x0.6 thread that is compatible with many telescopes. The 1.25-inch polarization filter is the universal lunar and planetary filter for the beginning.
Rotating setting: By turning the filter housing, the light permeability can be gradually adjusted from 1 % to 80 %, which enables fine control of the scene and performance as required.
