The Orion 1.25 inch 13 percent Transmission Moon Filter reduces glare so you can see more lunar detail and surface features with your telescope.
Metal filter cell threads directly into the 1.25 inch barrel of your telescope eyepiece.
Especially useful for large aperture telescopes through which the light of the Moon can be extremely overwhelming.
Telescope eyepiece filter transmits only 13 percent of the incoming light, boosting contrast and ability to discern detail on the Moon.
Perfectly neutral color will not alter the natural color of the Moon.

We are able to see the Moon at night thanks to sunlight
reflecting off its rocky surface. When looking at the Moon
through a telescope, bright reflected sunlight can produce
significant glare. The Moon's disk, even at partial phases, is in
fact so intensely bright with reflected sunlight that observing
surface details can be challenging due to the overwhelming glare.
This glare can be so bright that it washes out most of the
interesting lunar features such as craters, rilles, mountains,
and valleys. The considerable brightness also reduces contrast on
our nearest neighbor in the solar system. To improve contrast and
tone down glare easily, we recommend using a neutral-density 1.25
inch Orion 13 percent Transmission Moon Filter. This inexpensive
accessory threads directly into a 1.25 inch eyepiece barrel and
blocks 87 percent of the light gathered by the telescope, making
for more comfortable lunar views exhibiting higher contrast. Once
installed on a 1.25 inch telescope eyepiece, the Orion 13 percent
Transmission Moon Filter will bring out considerably more lunar
surface details thanks to the boosted contrast. Not only will
more surface features and details pop out, but you can study them
in greater comfort, thanks to Moon Filter reducing overall
brightness without altering color. This neutral-density telescope
eyepiece filter reduces irradiation, which is the distortion at
the boundary between light and dark areas, such as along the
lunar terminator. Using a Moon filter also helps conserve
dark-adapted vision while viewing the lunar surface, especially
when using big telescopes with 6 inches of aperture and larger.
The Moon is one of the most interesting objects in the night sky
to observe through a telescope. Its rugged surface is a feast for
the eyes of amateur astronomers, with fascinating craters,
mountainous highlands, and large, dark lunar seas formed by
ancient volcanic activity.
