The CLS broadband filter is designed to improve the visibility of deep-sky objects by reducing the effects of light pollution. Emission nebulae emit light primarily at specific wavelengths, such as Hα at 656 nm, Hβ at 486 nm, and OIII at 496/501 nm. This filter allows these wavelengths to pass through while blocking unwanted light from other sources.
