Apertura 1.25″ Neutral Density Filter 50% Transmission
This Apertura Neutral Density filter delivers enhanced image detail with 50% light transmission. This 1.25″ ND filter threads into 1.25″ eyepieces, diagonals, and other accessories. Perfect for observing the Moon, the Apertura Neutral Density Filter will darken your view and minimize the amount of light that reaches the eyepiece. As an added bonus this filter has threads on the top side which allows for the stacking of additional filters so you can customize your observing experience. A protective case is included for safe storage when not in use.
