Optolong Clear Sky Clip Filter for Nikon Z Cameras

Optolong CLS-CCD Light Pollution Filter for Nikon Cameras with Z-mount

The CLS-CCD 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 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 (skyglow). Together with the highly transparency in main nebula emission lines at OIII (496 nm and 500 nm), H-beta (486 nm), NII (654 nm and 658 nm), H-alpha (656 nm) as well as SII (672 nm), the filter is suitable for enhancing the contrast and details for photograghic purpose at light pollution area.

Main Use and Performance

CLS-CCD is different from CLS due to cut-off of infrared wavelength from 700-1100 nm

Work well on most emission nebulae, planetary nebulae and supernova remnants

Noticeable boost in contrast and visibility of the fainter outer detail

Light pollution filters do not completely 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 Optolong are not designed for sun observation. DO NOT LOOK AT THE SUN WITH OPTOLONG FILTER. You would be BLIND if you fail to observe the warning.
