    Products Features

    The 1-1/4" O-III narrowband filter isolates just the two doubly-ionized oxygen lines (496 and

    501nm lines) emitted by planetary and emission nebulae, while effectively blocking the rest of

    the overall spectrum of light. It results in extreme contrast between the black sky background

    and the faint photons of O-III light needed for detailed views of the Veil, Ring, Dumbbell,

    Crescent and Orion nebulae, as well as other objects. As lights of all other wavelengths are

    filtered out, the image presented to you have superior contrast and clarity compared to other

    broader band filters.

     

    Each filter has an ultra hard, vacuum-deposited coating carefully designed to block all of the

    visual spectrums ranging from 400 to 700 nm. This then eliminates the un-natural colored

    halos surrounding bright stars common with O-III filters with less sophisticated coating

    technology.

     

    Available in 1.25” and 2”.

     

    Highly recommended and excellent for viewing all nebulae that glow in the Oxygen III region.
