The 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 high transmittance in main emission lines of nebulae, namely O-III(496nm and 500nm), H-beta (486nm), N-II(654nm and 658nm), H-alpha(656nm) and S-II(672nm), the filter is suitable for enhancing the contrast and details for both visual and photograghic purpose at sub-rural area.
Compatible with all APS-C sized Canon EOS cameras. Not for full frame cameras.
Suitable for CCD cameras and DSLRs. CLS with wider pass-band than UHC and hence is more favored when observing under mild to moderate light pollution and more natural color retention. Light pollution filters neither nullify light pollution nor make nebulae brighter. In most situations, they just enhance the contrast of a nebula and reduce the background brightness. The brightness of the nebulae is not increased.
WARNING:
Optolong filters are not designed for solar observation. DO NOT LOOK AT THE SUN WITH ANY OPTOLONG FILTER as permanent eye damage will be the result.
