About Optolong UHC Clip Filter For DSLR Cameras
The UHC (Ultra-High Contrast) broadband filter is designed to improve the visibility of various deep-sky objects. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lighting such as mercury vapor lamps, both high & low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (skyglow). The filter is highly transparent in the main nebula emission lines at OIII (496nm and 500nm), H-beta (486nm), NII (654nm and 658nm), H-alpha (656nm) as well as SII (672nm). The filter is suitable for enhancing the contrast and details for both visual and photographic purpose in suburban and rural areas with heavy light pollution.
