This neutral density filter transmits light uniformly across the entire visual spectrum. It serves as an excellent filter to reduce glare and irradiation when observing the Moon, especially for telescopes of 6 inch or larger aperture.
The ND96 filter may also be employed in the splitting of close double stars where one of the binary pair signficantly exceeds the other in brightness. Threads into the barrels of all Meade (and most other brands) 1.25" eyepieces.
