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 1.25" Orion 13% Transmission 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.

An excellent filter for beginniners!

This moon filter is a great way to explore the moon for beginniners! This filter can reduce the glare of the bright moon so you can explore the moon easily. But for experts I would recommend to get a Orion Poliarzing Filter (...). This is because somtimes the moon is too dark. With a poliarzing filter you can adjust the filter from 1-40%. For beginniners I would strongly recommened this filter but for experts I would get a Poliarzing filter.More detail ...
