Baader Planetarium 2" Double Polarizing Filter
Baader's Double Polarizing Filter fits 2" eyepieces/threads. This dual filter system is designed with two filters that can be rotated against each other to consistently achieve an optimal brightness level for observing the moon, no matter the current phase. Plus, with an objective Astro Solar Film sun filter, it can also be used for solar viewing.
While one filter in this system is rotatable, the other is a regular filter that can be unscrewed and serve as a single polarization filter which is useful for a Herschel Wedge.
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.
