Optolong CLS Filters Telescope Mounting Clamp 1400mAh lithium batteryThe Optolong CLS (City Light Suppression) broadband filter is designed to improve the visibility of various deepsky objects. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lightings including mercury vapor lamps, both high & low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i. e. skyglow). Together with the highly
