Clip Filter for Nikon Full Frame UHC

The Ultra High Contrast (UHC) broadband filter was developed to improve the visibility of a range of deep sky objects.

This is achieved by reducing the transmission of some of the wavelengths involved in light pollution. In particular, those produced by artificial lighting such as mercury vapour lamps. But also by the blocking the light from sodium vapour lamps and the unwanted 'sky glow' effect. As well as being highly transparent to the main nebula emission lines at OIII (496nm and 500nm), H-beta (486nm), NII (654nm and 658nm), H-alpha (656nm) and SII (672nm), the filter is also suitable for improving contrast and detail, for both visual and photographic astronomy, away from rural areas with high levels of light pollution.
