Alpine Astronomical Baader Single Polarizing Filter (1.25″)(Alpine Astronomical Baader Single Polarizing Filter 1 25)

Use the 1.25″ Alpine Astronomical Baader Single Polarizing Filter to eliminate extraneous light and improve contrast during lunar and planetary observations. It is made with standard 1.25″ threads to fit on just about any eyepiece. The filter can also be used to adjust the image brightness during solar observations and improve image quality when used in conjunction with primary solar filters such as Alpine’s Herschel Prism or AstroSolar Safety Film. This is not a solar filter, and proper certified solar filters must be used to avoid permanent damage to eyes, up to and including blindness.
