Use the Alpine Astronomical Baader 0.6 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.

Its housing is made to fit most 1.25″ eyepieces and has female threads for stacking it with other ND and colored filters to further improve views when observing planets and other objects. This iteration of the ND filter line has an optical density of 0.6, with 25% transmission and a reduction factor of 4making it ideal for viewing and photographing the moon at its half-moon phase.

The filter can also improve solar viewing, but only as a secondary pre-filter stacked with a primary dedicated solar filter. Failure to use a dedicated solar filter may result in permanent eye damage up to and including blindness.
