    Baader 2" mounted f/2 Halpha OIII SII filters

    DESCRIPTION
    Specially engineered for ultra-fast systems like Celestron’s RASA, this Baader narrowband filter set includes H-Alpha (3.5 nm), O-III (4 nm), and S-II (4 nm) filters in standard 2" mounts. The Reflex-Blocker™ coatings suppress halos, and the Life-Coat™ technology ensures durability for a lifetime. Designed for perfect 1:1:1 exposures on modern CMOS sensors, each filter is sealed, has blackened edges, and includes a telescope-side marker for correct orientation. These filters maximize contrast and resolution, even under heavily light-polluted skies.
