  • Antlia ALP-T Dual Band Ha&OIII 3nm - Overview

    The Antlia ALP-T Dual Band Filter Set is a high-performance toolset designed for astrophotographers who demand precision, contrast, and exceptional image quality. This set includes the Ha&OIII 3nm Filter and the SII&Hβ 3.5nm Filter, providing unmatched narrowband imaging capability for capturing deep-sky objects with remarkable clarity and detail.

    High Signal-to-Noise Ratio

    Superior imaging in challenging light conditions.

    Versatile Applications

    Suitable for capturing traditional RGB images or creating artistic false-color palettes.

    Easy Integration

    Compatible with optics slower than f/4, with high-speed versions available for faster setups.

    Ha&OIII 3nm Filter

    This dual narrowband filter isolates the H-alpha (656.3nm) and OIII (500.7nm) emission lines, optimized for use with color cameras. With a Full Width Half Maximum (FWHM) bandwidth of 3nm, it effectively blocks unwanted wavelengths, including light pollution, moonlight, and airglow. The result is an enhanced signal-to-noise ratio and strikingly detailed nebula images.

    • Precise Transmission: Passes H-alpha and OIII lines exclusively for improved contrast in celestial images.
    • Exceptional Filtering: Blocks optical density (OD) 4.5 on stray wavelengths, suppressing light pollution and enhancing nebula visibility.
    • Ideal for OSC Cameras: Designed for color cameras, with applications in luminance filtering for monochrome cameras.
    • Flat-Top Bandpass: Reduces spectrum shifts for consistent imaging performance, even under varying conditions.
