Explore Scientific 2" ND 0.9 Filter
Explore Scientific 2" ND 0.9 Filter
The Explore Scientific 2" 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 that accepts 2" eyepieces.
The Explore ND Filter has a density of 0.9 and a transmission of 13%, and comes in a 2" metal cell that can be threaded easily onto the 2" barrel of an eyepiece, Barlow, or other accessory. Besides working great on the Moon, it will help split close double stars where one star is much brighter than the other. Neutral density filters also help decrease brightness when using your telescope for terrestrial viewing on a bright, sunny day.
