    ZWO 1.25" OIII 7 nm Filter

    The ZWO OIII 7nm Filter is mounted in a metal 1.25" cell and comes in a protective plastic case. 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.

    OIII, or doubly ionized oxygen, emits light in the blue/green, or the teal portion of the spectrum near 500 nm. Planetary nebulae and supernova remnants emit most of their light in the OIII line. OIII is considered the second most popular narrowband imaging filter (behind H-a), and when used in conjunction with H-a and SII, your images will get that tri-color "Hubble Look".
