The result is extreme contrast between the black sky background and the faint photons of OIII light needed for detailed views of the Veil, Ring, Dumbbell, Crescent and Orion nebulae, among other objects. Each Celestron OIII 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 ...

This is a great filter for viewing emission nebulae. This filter easily doubles the size and greatly increases contrast on several dozen nebulae.
