Baader Planetarium 1.25" Polarising Filter

Single Polarizing Filter 31.7mm

Enhances contrast during planetary observation. 
Also extremely Useful for solar work in conjunction with Baader Herschel Wedge Prism (#2956500V or #2956500P)

Many features, including:

• Put the Baader Solar Polarization Filter between the Baader Herschel Wedge and the eyepiece and easily adjust the brightness of the solar image.
• The 1.25" model (sold here) can attach directly to 1.25" eyepiece.
• If you are using both 1.25" & 2" eyepieces, a 2" Polarization filter is recommended, along with a T2 2"-to-1.25" Adapter, such as #2408190, so that you can conveniently switch eyepieces regardless of their barrel size.
• The Baader Solar Polarization Filter achieves the optimum brightness for maximum visual contrast at any magnification.
• Planoptically polished.

Do not use this polarization filter on the Sun except as part of the Herschel Wedge chain. Immediate eye damage will result.
