Explore Scientific ND 0.9 13% Neutral Density / Moon Filter - 2" # 310240.
The Explore Scientific 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 with any telescope 4" (10.2cm) and larger. 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.
