Baader Double Polarizing Filter

To screw into 1¼ or 2" eyepieces/threads. The two filters can be rotated against each other to always be able to achieve comfortable brightness level for moon observations, independent of moon phase. The Baader Double Polarizing Filter can also be used for solar observations in combination with an objective sun filter from Astro Solar Film.

The filter can also be unscrewed. A filter has a normal version, the other rotatable. The filter with the normal version can be used as normal single polarization filter which is useful for a Herschel Wedge.

Important Information for Observing the Sun

Polarizer and neutral density filters need additional filtering (for example, Herschel Prism or Astro Solar Safety Film) before the eyepiece of the telescope for observations of the sun. Using without the appropriate filters can cause damage to the these filters and eyesight.
