    Experience unparalleled astrophotographic results with the Antlia H-Alpha 4.5nm Edge filter, designed to elevate your deep-sky imaging capabilities. This meticulously crafted filter offers exceptional performance at an accessible price point, making it a valuable asset for both seasoned astrophotographers and those embarking on their celestial journey.

    Key Features:

    Exceptional Narrowband Isolation: The 4.5nm bandpass meticulously targets the Hydrogen Alpha line (656.3nm), offering a 1.5% transmission window within the visible spectrum. This translates to superior signal-to-noise ratio and breathtaking contrast, revealing the intricate details of nebulae with remarkable clarity.

    Unrivaled Contrast & Light Suppression: Experience a deeper, darker background thanks to the advanced edge-blackening technology. This effectively eliminates stray light and internal reflections, ensuring the nebulae become the true focal point against a void of inky blackness.

    Uncompromised Performance for Fast Optics: Utilize the filter without sacrificing image quality, even with systems as fast as f/3. The Antlia Edge delivers exceptional performance with Hyperstar and RASA setups, capturing fleeting details with utmost precision.

    Rigorous Quality Control & Parfocality: Each filter undergoes meticulous individual testing, ensuring they meet the highest quality standards. The tight tolerance of the substrate guarantees a maximum deviation of only ±0.05, making them perfectly parfocal for seamless switching between filters.

    Simplified Workflow: Eliminate the need for a separate IR-cut filter. The Antlia Edge effectively blocks both ultraviolet and infrared light, streamlining your astrophotography setup and maximizing exposure time for capturing faint details.
