The
Moon Filter is a precision neutral density filters that spreads
the Lunar intensity uniformly over the visual spectrum. When
the Moon is full or nearly full, it's disk appears blindingly
bright with reflected sunlight. The glare washes out most of
the craters, and other surface details. Moon filter reduces
glare and intensity, thereby enabling you to study Lunar features
in greater comfort and without spoiling your night vision.Reduces
irradiation, which is the distortion at the boundary between
light and dark areas such as along the Lunar terminator. For
Visual use simply thread these filters into the 1.25" eyepiece
barrel of any imported Astro Eyepiece. |
