Explore Scientific 1.25" Variable Polarizing Filter

Explore Scientific 1.25" Variable Polarizing Filter

DESCRIPTION
The Explore Scientific 1.25" variable polarizing filter provides continuously adjustable light transmission between 40% and 1% by rotating the filter housing. It is particularly effective in compensating for high-contrast variations, notably during Moon, planetary, or solar observations (with appropriate solar filter only). Especially useful when using a Herschel wedge, it delivers optimal viewing comfort even with large aperture optics. The neutral grey tone ensures natural color reproduction.
Made from high-quality optical glass and black anodized aluminum, this filter features both male and female 1.25" threads, allowing stacking with additional color filters. It comes with a protective box and is covered by a 10-year manufacturer warranty.
