The 2"Svbony OIII narrowband filters isolates just the two doubly-ionized oxygen lines (495.9nm&500.7nm) emitted by planetary and emission nebulae, while blocking the rest of the overall spectrum of light.


Each Svbony filter has an ultra hard, vacuum-deposited coating carefully designed to block all of the visual spectrum ranging from 400 to 700 nm This eliminates the un-natural colored halos surrounding bright stars common with OIII filters of less sophisticated coating technology.
