This variable polarizing filter is designed for universal use and allows for continuous adjustment of the image brightness. It proves very useful for individually compensating for significant contrast differences on various observed objects, such as the moon, planets, and the sun.

Sun observation must exclusively be performed with a suitable solar filter. If you are using a Herschel solar telescope and a large aperture objective, the variable polarizing filter can reduce the brightness of the observed object to a comfortable level.

The filter has a wide adjustment range from 40% to 1% light transmission and a neutral gray filtering effect, creating an image that is both comfortable and authentic. It is very simple to use: by turning the two halves of the casing, the intensity of the filter can be adjusted to your preference.

The filter is equipped with 2" filter threads on both sides (inside/outside) to allow for the simultaneous use of other color filters. It is made of high-quality optical glass, and its casing is made of black anodized aluminum.
