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.
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.
