Bintel GSO ND96 Moon 50% 1.25 Inch (Density 0.3)

The Bintel ND96 50% Neutral Density filters reduce the glare by only partially transmitting (only 50%) of the reflected light uniformly across the entire spectrum. Not only will you see more surface features, but you can study them in greater comfort. These filters also reduce irradiation, which is the distortion at the boundary between light and dark areas, such as along the lunar terminator. Screws directly into the eyepiece barrel.

The Moon’s disk, even at partial phases, is intensely bright with reflected sunlight. The glare washes out most of the craters, rilles, and other surface details from view, particularly in telescopes of 6 inch aperture and larger.

With standard filter threads (M25.5 x 0.6) it can be screwed into almost any 1.25″ eyepiece, 1.25″ diagonal or can be stacked with other coloured filters to enhance lunar and planetary detail.

The ND96 filter may also be employed in the splitting of close double stars where one of the binary pair significantly exceeds the other in brightness.

Comes in plastic case for clean, safe keeping.
