Orion 05662 1.25-Inch 13 Percent Transmission Moon Filter (Black)
Style:Single 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.
