The Moon's disk, even at partial phases, is intensely bright with reflected sunlight. The glare washes out most of the craters, rilles, and other surface details from view.
Orion's Moon Filter reduces the glare, allowing transmission of only 13% of the reflected light. Not only will you see more surface features, but you can study them in greater comfort. This telescope filter reduces irradiation, which is the distortion at the boundary between light and dark areas, such as along the lunar terminator.
The 1.25" Orion 13% Transmission Telescope Moon Filter is especially useful to owners of large-aperture telescopes, in which the Moon's brightness can be overwhelming. It uniformly reduces light over the entire visible spectrum. Screws into threaded telescope eyepiece barrel.
