About
A light-pollution filter for astrophotography that blocks the emission lines of sodium and mercury street lighting and natural airglow while passing a wide band, so stars are dimmed less than with a UHC. An integrated IR-blocking layer suits cameras without their own IR-cut filter. Clip-in for Canon EOS M bodies, Standard substrate.
