Orion Moon Filters

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. The Orion Moon Filter reduces the glare, allowing transmission of only 13% or 25% of the available light, depending upon the model chosen. Not only will you see more surface features, but you can study them in greater comfort. The filter reduces irradiation, which is the distortion at the boundary between light and dark areas, such as along the lunar terminator.
