The Moon is one of the most interesting objects to observe through a telescope. Its many craters, rugged mountains, deep canyons and large, dark lunar "seas" formed by ancient volcanic activity are all fascinating sights to behold in any size telescope. Make all your telescopic views of the Moon even better with the affordable 1.25" Orion E-Series Moon Filter.

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 it can be a challenge to observe detailed surface features. The bright glare of the Moon can often wash out fine details of the most interesting lunar features to study in a telescope.

To improve contrast and tone down glare easily, we recommend using a neutral-density 1.25" Orion E-Series 13% Transmission Moon Filter. This inexpensive filter threads directly into a 1.25" eyepiece barrel and blocks 87% of the light gathered by the telescope, making for more comfortable lunar views which exhibit higher contrast. Once installed on a 1.25" telescope eyepiece, the Orion 13% Transmission Moon Filter will bring out considerably more detailed views of lunar surface details. 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 also helps reduce irradiation, which is the distortion at the boundary between light and dark areas such as along the lunar terminator, for a more pleasant viewing experience. Using a Moon filter also helps conserve dark-adapted vision while viewing the lunar surface, especially when using larger telescopes.

The Moon is a delightful target for backyard astronomers of all skill levels. Whether you're just getting started in the hobby of amateur astronomy, or are a more seasoned stargazer, improve your views of the Moon easily with the inexpensive 1.25" Orion E-Series 13% Transmission Moon Filter!
