The Astronomik CLS-CCD filter is a specialized tool designed for astrophotography under light-polluted skies, particularly for DSLR cameras modified for astronomical use. It enhances the contrast between deep-sky objects and the background by blocking artificial light sources such as sodium- and mercury-vapor lamps, while allowing important emission lines like H-alpha, H-beta, and OIII to pass through.
