Alpine Astronomical Baader 1.8 Neutral Density Filter (1.25")

Use the Alpine Astronomical Baader 1.8 Neutral Density Filter to reduce the amount of light coming into your eye during lunar observation and improve the view and contrast. The lens surfaces are fully multi-coated with Phantom Group seven-layer optical coatings. This maximizes light transmission across the entire visual spectrum, stepping down the light throughput while maintaining color-neutral views without reflections, ghosting, or stray interference light.
