  • ZWO Narrowband OIII Filter - 7nm - Overview

    Astrophotography Product

    The ZWO Narrowband OIII Filter - 7nm is an advanced astrophotography filter designed to isolate the oxygen-III emission line at 500.7 nm. This filter enhances the visibility of nebulae and other celestial objects by reducing interference from unwanted light sources. Whether imaging under light-polluted skies or moonlit conditions, the OIII filter delivers outstanding contrast and detail for your deep-sky imaging sessions.

    7nm Bandpass for Precision Imaging

    The narrow 7nm bandpass ensures precise transmission of the oxygen-III emission line while effectively blocking unwanted wavelengths for superior contrast and clarity.

    Enhanced Nebula Imaging

    Designed to reveal intricate structures in planetary and emission nebulae, such as the Veil Nebula, Dumbbell Nebula, and the Heart Nebula.

    Light Pollution Suppression

    Ideal for urban astrophotography, this filter minimizes interference from streetlights and skyglow, allowing for clear, detailed captures.

    High Transmission Rate

    Ensures maximum light throughput at the OIII wavelength, making it easier to capture faint details in celestial objects during long exposures.

    Superior Optics

    Manufactured with premium optical glass and multi-layer coatings, the filter minimizes halos and reflections while providing excellent durability.

    Standard Sizes for Versatility

    Available in multiple sizes (1.25", 2", etc.) to fit ZWO cameras, filter wheels, and other astrophotography equipment, ensuring compatibility across various setups.

    Why Choose This Product

    Applications

    • Tri-Band Narrowband Imaging: Combine the OIII filter with H-alpha and SII filters to create stunning, true-color narrowband images of deep-sky objects.
    • Light-Polluted Imaging: Achieve high-quality astrophotography results even from heavily light-polluted areas.
    • Moonlight-Friendly Imaging: The OIII filter allows you to continue imaging under moonlit skies without significant degradation in image quality.
