Sky Mentor 1.25" Variable Polarizer Filter - TA189 classic With its 55 lb loadAdjust the brightness level of the Moon, Venus, and other bright objects with the Sky Mentor Variable Polarizer. A standard Moon Filter is similar to a pair of sunglasses. They work fine, but sometimes the scene is too dark or too bright, and theres not a lot you can do about it. A variable polarizing filter is much more flexible than a Moon filter. It allows you to set the percentage of attenuation by turning the top section of the two piece filter.
