The ND filter reduces the overall brightness of an image to cut down glare while viewing bright astronomical objects through a telescope. Baader balances each dielectric coating stack to avoid the ghosts and annoying halos that plague other manufacturers filters. Unlike most other filters, Baader filters are truly designed to be stacked and combined. This is possible due to the high optical quality and highly efficient anti-reflection multicoatings. The ability to combine filters opens up many interesting possibilities, permitting unique spectral characteristics unachievable with any single filter.
