Filter Optolong anti-light pollution filter CLS EOS-C

OTLOG-CLS-EOSCF

77.64 83.00 -5.36 VAT excl.

The CLS (City Light Suppression) broadband filter is designed to improve the visibility of deep space objects by selectively reducing transmission at wavelengths typical of polluting artificial lights (mercury vapor and high and low pressure sodium lamps) and also natural light caused by the emission of neutral oxygen in the atmosphere (skyglow).
