Designed for color CCD and unmodified DSLR cameras, this durable aluminum filter enhances deep-sky visual and photographic clarity, making it a must-have for urban astronomers seeking crisp, high-contrast celestial images. ## Description The City Light Suppression broadband filter is designed to improve the visibility of various deep sky objects. SVBONY city light suppression 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 including mercury vapor lamps; both high and low pressure sodium, vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere, such as sky glow. Extinction Treatment: aerometal material precise CNC machining sand blasting process black anodized finish extinction treatment to prevent reflection laser. Planetary rotation system offers precision and homogeneity of coatings ensuring high value on transmission of pass-band and optical density of off-band. Ultra-thin filter cell minimize vignetting by possible. 90% transmission of main nebula emission lines (i.e. Ha 656nm, OIII 496nm&500nm, SII672nm and H-beta 486nm). 0.1% transmission of off-band, specifically the major emission lines of artificial light pollution (i.e. Na 589nm, Hg 435nmand 578nm). Compatible with color CCD cameras and unmodified DSLRs. CLS filter: engraving no fading CLS with wider pass-band than UHC and hence is more favored when observing under mild to moderate light pollution. Light pollution filter do not eliminate the effects of light pollution or increase the object’s brightness; in many cases, they increase the contrast between nebula and night sky, not brightening the nebula. Warning: the filters of SVBONY are not designed for sun observation, don not look directly into the sun with SVBONY filter, otherwise it will burn the eyes. 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; CLS filter is suitable for enhancing the contrast and getting more details for both visual and photographic purpose at sub-rural area.
