Orion 05662 1.25-Inch 13 Percent Transmission Moon Filter (Black)

Description

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.

Features:

  • 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

  • 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
