The Astronomik CLS blocks the light of the spectral lines of mercury and sodium-vapor lamps and lets the largest part of the visible light and H-alpha emissions pass.
These contrast-enhancing filters are designed to block out the wavelengths of light emitted by mercury-vapour light and other common causes of light pollution.
