Orion Moon Filter

The 1.25" Orion Moon Filter reduces glare, allowing transmission of only 13% of the reflected light. Not only will you see more surface features, but you can study them in far easier and 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 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 Moon Filter

This Orion 2" 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.
