Baader Planetarium 1.25" Single Polarizing Filter

Thread this Baader Single Polarizing Filter into 1.25" eyepieces to reduce brightness while increasing contrast for lunar and solar observations. It can be used with the Baader Herschel Wedge to easily adjust brightness by rotating the filter/eyepiece combination when the filter is placed between the Herschel Wedge and the eyepiece.

Important Information For Observing The Sun

Polarizing and neutral density filters require additional filtering such as a Herschel Prism or Astro Solar Safety Film before the telescope eyepiece for safe solar viewing. Observing without the proper filters can cause severe damage to both these filters and your eyes.

Ryan D. ★★★★★

I was skeptical about spending extra on a filter, but this one really cuts lunar glare without washing out the surface detail like cheaper filters do. Threading it on my 1.25" eyepiece was smooth and secure.

Ruby X. ★★★★★

Moon viewing went from a glaring white blob to a crisp disk with visible maria—the contrast boost is honestly dramatic for such a small piece of glass. Screws into my eyepiece snugly, no wobble, and it cuts the glare down to a comfortable level even at high power.

Lily ★★★★★

The threads on this filter screw into my eyepieces smoothly without any cross-threading, which I appreciate. It really cuts down glare on the moon, letting me see crater details I’ve been missing. A small but noticeable upgrade for lunar viewing.
