Baader Double Polarizing Filter 1¼"

  • Baader Double 1.25" Polarizing Filter - Ideal for solar and planetary observations.
  • For solar work in conjunction with Baader AstroSolar Safety Film or Baader Herschel Wedge Prism (never use any eyepiece filter for solar observation without objective front filter).
  • Enhances contrast during planetary observation.
  • Sealed coating edges prevent air or moisture from entering.

The filter can also be used with a Baader Hershel Wedge to provide an adjustable brightness. Positioned between the Baader Hershel Wedge and Eyepiece the filter/eyepiece combination can then be rotated to adjust brightness.  To screw into 1¼ or 2" eyepieces/threads. Useful in Lunar and Solar observations to limit brightness and increasing contrast. Polarizes the transmitted light.

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.
