Main Products

Item Description

Size:1.25 inch 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 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 getting more details for both visual
and photographic purpose at sub-rural area Multi layers anti-reflection
coating.Non cementing optical substrate coatingUltra-thin filter cell minimize
vignetting by maximize possible Aerometal material precise CNC machining sand
blasting Process black anodized finish extinction treatment to prevent
reflection laser engraving no fading CLS with wider pass-band than UHC and
hence is more favored when observing under mild to moderate light pollution
