Baader 2" mounted f/2 Halpha OIII SII filters
Set of mounted 2" H-alpha, O-III, and S-II filters optimized for f/2 CMOS imaging.
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.
