  • Enhances Overall Image Contrast
  • Standard 2" Eyepiece Filter Threads
  • Allows Solar Viewing with Proper Filters

Use the Alpine Astronomical Baader Double Polarizing Filter to eliminate extraneous light and improve contrast during lunar and planetary observations. It is made with standard 2" threads to fit on just about any eyepiece. The filter's double rotating filter cells allow you to precisely adjust the image brightness during lunar, planetary, and solar observations and improve image quality. For solar viewing the polarizing filter must be 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.

    Scent and application does not irritate my very sensitive lungs and skin
    I am having excellent luck with this sunblock! I have sensitive skin and am extremely sensitive to some aerosol and scented products. This has not been an issue with me in any way. We do apply this outside for more ventilation. I have not used this on small children. This has primarily been tried by adults in my household. It’s super easy to apply, not oily, and so far is providing sun protection. I have not used this and then entered water. Our use has been for just everyday running around. It has not irritated anyone’s skin and no one has been burned by the sun- so gonna say it’s a win. This is very likely my new brand. I will update this review over the summer with how it holds up at the beach and pool. It’s doing a great job for basic outside recreation and play
