SV139 Telescope Filter 1.25 inches ND Neutral Density for Moon Observation

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

Features:

• Made of high definition optical glass with high light transmission
• Aluminum alloy sealing ring for better sealing and prevention of dropping or loosening
• Reduces distortions between light and dark areas at the edge of the Moon, helping to preserve dark adaptation when observing the lunar surface

Usable with different astronomical telescopes for which the light from the Moon can be extremely dazzling.
