Product Details

  • This ND96 Moon Filter threads onto 1.25-inch eyepieces.

    Eyepiece filters are an invaluable aid in lunar and planetary observing. They reduce glare and light scattering, increase contrast through selective filtration, increase definition and resolution, reduce irradiation and lessen eye fatigue.

    Third Planet Optics filters are made of high quality, solid plane parallel glass with excellent homogeneity. They are anti-reflection coated to prevent glaring and ghosting. All eyepiece filters are threaded to fit most 1.25-inch eyepieces and offer a full 26mm clear aperture. Comes with a hinged, plastic case to keep your filter safe and clean when not in use.

    A ND96 Filter (0.9 density, 13% transmission) is used most often on the Moon, since it reduces glare while transmitting light in a uniform manner across the entire spectrum. It is also a great filter for viewing the phases of Venus, or for splitting close double stars when one star is significantly brighter than the other.

    Best for 4-inch aperture and larger telescopes.
