Baader double Polarizing-Filter with rotating cell mount offers perfect light management when viewing bright objects. The filter is ideal filter for sun and Moon observation and contrast enhancement in planetary observations. Adjustments can be made by rotate the filter in its cell to the variable brightness of the image being viewed to suit current magnification. To screw into any 1¼" or 2" eyepieces, the Baader Herschel prism rotate the filter in its cell and adjustments can be made to the variable brightness of the image being viewed to suit current magnification. The filter cell is Planoptically polished to enhance performance.

- Great for the observation of sun and Moon
- Planoptically polished to enhance performance
- Features contrast enhancement in planetary observations
- Offer perfect light management when viewing bright objects
- Adjustments can be made by rotate the filter in its cell to the variable brightness of the image being viewed to suit current magnification
- The reflected image of the sun from the Herschel prism is already partially polarized
- For solar observation with a Herschel prism, you do not need a double polarizing filter
- When used with an Astro Solar film, however, you need a double pole filter to continuously further mitigate the unpolarized sunlight
Note: If necessary please order the simple polarizing filter for further light attenuation
