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. \u003c\/p\u003e \u003cp\u003eIts housing is made to fit most 2\" 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 1.8, with 1.0% transmission and a reduction factor of 64�making it ideal for viewing and photographing the moon as it moves toward full.\u003c\/p\u003e \u003cp\u003e The filter can also improve solar viewing, but \u003cem\u003eonly\u003c\/em\u003e as a secondary pre-filter stacked with a primary dedicated solar filter.
