SV139 Telescope Filter 1.25 Inch ND Neutral Density for Moon Observation - W9108A

SV139 telescope filter 1.25 inches ND Neutral Density for lunar observation

The neutral density filter reduces the amount of light reaching the film without affecting colors and reduces glare, allowing for more lunar details and surface features to be seen through your telescope.

Features:

• Made from high-definition optical glass with high light transmission
• Sealing ring made of aluminum alloy for better sealing and prevention of dropping or loosening
• Reduces distortions between bright and dark areas at the edge of the Moon, helping to preserve dark-adapted vision when observing the lunar surface

Usable with various astronomical telescopes for which moonlight can be extremely dazzling.
