    Antlia 8-EL UHC Pro Visual Enhancer Filter – 2 Inch

    The Antlia 8-EL UHC Pro Visual Enhancer 2" filter is specifically designed for visual observation of celestial objects. It is optimized to reduce moderate light pollution while maintaining excellent color balance, making it ideal for observing emission nebulae, planetary nebulae, and other deep-sky objects.

    Enhanced Transmission Lines:

    This filter selectively enhances key emission lines through its high-transmission design:

    • 486.1 nm (H-beta) — 95% transmission

    • 495.9 nm (OIII) — 95%

    • 500.7 nm (OIII) — 95%

    • 654.8 nm (NII) — 95%

    • 656.3 nm (H-alpha) — 95%

    • 658.3 nm (NII) — 95%

    • 671.6 nm (SII) — 95%

    • 673.1 nm (SII) — 95%

    Thanks to this optimized transmission (>95%) and the suppression of sodium light pollution, observers can see fine structural details in faint objects even under suburban or moderately light-polluted skies.
