    The control of variable light transmission is highly desirable for lunar observations because the Moon's brightness varies with its phase and with the aperture and magnification of the telescope you are using

    This Orion Variable Polarising Filter effectively reduces the blinding brightness of the Moon at at full Moon phase at the same time enhances many of the Moon's details. Mountains, valleys, and of course all those stunning craters. Reducing the overall brightness of the Moon helps reveal more surface details so you get the most out of each view. 

    The Moon is one of the most enticing targets to view in the night sky. Thanks to its big, bright appearance and intriguing landscape features, the Moon is a favored sight by amateur astronomers all over the world. The Moon is in fact so bright with reflected sunlight, especially during a Full Moon, that it can overwhelm astronomers with distracting and view-degrading glare. The specialised 1.25" Orion Variable Polarising Filter for 1.25" telescope eyepieces provides an elegant solution by toning down the brightness of the lunar surface so you can enjoy optimised contrast in each and every view of our nearest neighbour in the solar system.   

    To view the Full Moon with any degree of clarity would require a significant amount of dimming, closer to the 1% transmission limit. On the other hand, when the Moon is a thin, waning crescent in the night sky, you'll get the best results with minimal darkening, closer to 40% transmission. The Variable Polarising Filter won't change the Moon's natural color, so your views will simply be optimised, not altogether altered.

    The 1.25? Orion Variable Polarizing filter consists of two high-grade glass polarising filters securely held in a rotating telescope eyepiece filter cell that allows you to vary the amount of light transmission over a wide range from 1% to 40%.
