Baader Ultra-Narrowband CMOS Filters
Baader Ultra-Narrowband filters are CMOS-optimized narrowband filters with a 3.5nm H-alpha and 4nm O-III and S-II passband. The tight bandwidth gives strong contrast on emission nebulae and helps under light-polluted skies or a bright Moon.
They are designed for telescopes at conventional focal ratios, while the Highspeed versions serve very fast optics. Choose the individual H-alpha, O-III or S-II filter, or the complete 3.5nm/4nm set for SHO imaging with a mono camera.
