This filter enhances the contrast of deep-sky objects while reducing the brightness of the sky background. Achieving this involves a complex transmission characteristic that allows the spectral lines of deep-sky objects to pass while suppressing various sources of light pollution. It effectively diminishes the unwanted sky background, known as "skyglow," caused by oxygen emissions in the atmosphere.

The LRGB filter set is specifically designed for astrophotography with monochrome CCD cameras, allowing you to capture high-resolution color images of the night sky. Unlike color CCD cameras, which use built-in color filters that reduce resolution, a monochrome camera paired with LRGB filters utilizes the full sensor for each exposure. This results in brighter, sharper images of deep sky objects.

Optolong Filters Clip Filter for Canon EOS APS-C CLS-CCD (59443)
168.16 $
Tax included
The CLS (City Light Suppression) broadband filter is designed to enhance the visibility of deep sky objects by reducing the transmission of certain wavelengths associated with light pollution. It is particularly effective at blocking light from artificial sources such as mercury and sodium vapor lamps, as well as minimizing the unwanted 'sky glow' effect. The filter remains highly transparent to the main emission lines of nebulae, including OIII (496nm and 500nm), H-beta (486nm), NII (654nm and 658nm), H-alpha (656nm), and SII (672nm).
