By selectively reducing the transmission of wavelengths of light pollution, specifically those produced by artificial lightings including mercury vapor lamps, both high \u0026amp; 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 transparent in 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 at sub-rural area.\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cb\u003e\u003cspan style=\"font-size: 18px;\"\u003eFeatures:\u003c\/span\u003e\u003c\/b\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e1.
