  • Antlia ALP-T Dual Band SII&Hβ 3.5nm - 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.

    SII&Hβ 3.5nm Filter

    The SII&Hβ filter captures the deep red Sulfur-II (672.4nm) and blue Hydrogen-Beta (486.1nm) emission lines, providing complementary spectral data to the Ha&OIII filter. It’s perfect for creating detailed narrowband images and vibrant false-color palettes.

    • Dual Narrowband Capture: Captures SII and H-beta lines simultaneously for rich spectral imaging.
    • Enhanced Imaging Contrast: Blocks optical density (OD) 4.5 on unwanted wavelengths, optimizing contrast even in light-polluted conditions.
    • Creative Color Palettes: Enables various combinations like H-O-Hβ or S-H-O for unique astrophotography.
