Fits 1.25" eyepieces/threads. The two filters of this double filter system can be rotated against each other to consistently achieve a comfortable 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.
Please Note: You cannot unscrew the two polarizing filters to create two single filters for using on, for instance, a Herschel Wedge. Doing so may cause them to be tilted to each other when threaded back together, resulting in degraded image quality or reflections. You can follow this link if you need a Baader Single 1.25" Polarizing Filter.
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.
