OPTOLONG CLS FILTER Tilter this is even better withThe Optolong CLS (City Light Suppression) broadband filter is designed to improve the visibility of emission deep sky objects. It selectively reduces the transmission of wavelengths of artificial light, specifically those produced by mercury vapour lamps, both high and low pressure sodium vapour lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i. e. skyglow). The high transmission in the main nebula emission
