Description

  • 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.
