About
A light-pollution filter for photographing nebulae, galaxies and clusters: it blocks the emission lines of sodium and mercury street lighting and natural airglow while passing most of the visible spectrum, so stars are barely dimmed. Unlike the CLS CCD it has no IR-blocking layer, so cameras without their own IR cut need one added. Clip-in for Canon EOS R full-frame bodies, Standard substrate.
