Description
The Beta Tools Filtre CMOS Baader O-III 2 (6.5 nm) is a narrowband filter optimized for CMOS astrophotography, transmitting the oxygen-III emission lines with a 6.5 nm bandwidth. It blocks most other wavelengths to increase signal-to-noise when imaging planetary and emission nebulae. The high-transmission optical coatings ensure uniform light passage across the aperture, and its standard filter threading fits into common 1.25-inch filter wheels and visual holders.
