Adjust 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 wor k fine, but sometimes the scene is too dark or too bright, and there’s 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. Simply attach the 1.25” threaded filter to a like-sized eyepiece or astro accessory barrel, and then slowly rotate the top half of the filter—it turns 360°—to achieve the results you desire. Now you can apply more filtering to a full moon and less to a beautiful crescent—it’s your call! Show more
