More information

  • The Askar 6nm Colour Magic Super Ha/OIII D1 Filter is a specialized 2-inch astrophotography filter designed to capture stunning images of emission nebulae. This dual-narrowband filter isolates both the H-alpha (Ha) and Oxygen III (OIII) emission lines, allowing astrophotographers to create detailed, high-contrast images of deep-sky objects with vibrant colors.

    Disclaimer

    This filter is designed for use with colour cameras. Ensure compatibility with your imaging setup before purchase.

    Filter Specifications

    The Askar Colour Magic Super SII/OIII D1 Filter features a narrow 6nm bandwidth, allowing it to effectively isolate the Ha and OIII emission lines while blocking unwanted light pollution. This precision helps to produce high-contrast images with excellent signal-to-noise ratio, even under less-than-ideal sky conditions.

    Dual-Narrowband Performance

    Askar 6nm Colour Magic Super SII/OIII D2 Filter - 2

    By combining SII and OIII wavelengths in a single filter, this D2 filter allows for more efficient data acquisition compared to using individual narrowband filters. It captures the red-orange (SII) and blue-green (OIII) emissions simultaneously, enabling the creation of striking false-color images with reduced total exposure time.

    High-Quality Construction

    Manufactured with precision optical glass and high-quality dielectric coatings to ensure excellent light transmission and minimal reflections. The filter is designed to maintain its performance over time, resisting degradation from exposure to moisture or varying temperatures.

    Versatile Application

    Ideal for imaging a wide range of emission nebulae, supernova remnants, and planetary nebulae. The 2-inch size ensures compatibility with many telescopes and camera setups, making it a versatile addition to any astrophotographer's toolkit.

    Enhanced Contrast

    The narrow 6nm bandwidth effectively suppresses light pollution and skyglow, allowing for high-contrast imaging even from light-polluted locations. This makes the filter particularly valuable for urban and suburban astrophotographers.

    Efficient Workflow

    By capturing both Ha and OIII data simultaneously, this filter streamlines the imaging process, reducing the need for filter changes and potentially allowing more data to be gathered in a single imaging session.

    Compatibility

    Designed for use with monochrome CCD or CMOS cameras. The 2-inch size fits standard filter wheels and telescope focusers. Always check your specific equipment requirements to ensure proper fit and performance.
