    ZWO Narrowband Filter Set with 36mm OIII, SII, and H-Alpha Filters

    These ZWO 36mm filters are unmounted. ZWO narrowband filters are fine-optically polished to reach an accuracy of 1/4 wave. Their performance is further enhanced by multiple layers of anti-reflection coatings.

    ZWO 36mm Unmounted OIII Filter

    OIII, or doubly ionized oxygen, emits light in the blue/green, or teal portion of the spectrum near 500 nm. Planetary nebulae and supernova remnants emit most of their light in the OIII line.

    ZWO 36mm Unmounted Ha Filter

    Hydrogen-Alpha is the most dominant emission line in star-forming regions. H-Alpha light is created by atomic hydrogen and is responsible for the red color seen in most nebulae.

    ZWO 36mm Unmounted SII Filter

    Sulfur is in the deep red of the spectrum near 672 nm. When combined with H-alpha and OIII, these three filters will produce images with colors that are reminiscent of those taken by the Hubble Space Telescope.
