Orion - Moon Filter 13 percent Transmission 1.25 inch

Cures Moon-Watching Washout and Eyestrain
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.

Our 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. The filter reduces irradiation, which is the distortion at the boundary
between light and dark areas, such as along the lunar terminator.

The Orion Moon Filter is especially useful to owners of large-aperture scopes, in which the Moon's brightness can be
overwhelming. It uniformly reduces light over the entire visible spectrum. Screws into threaded eyepiece barrel.
