UHC Filter 1.25 Inches to Reduce Light Pollution in Astrophotography

UHC filters or light pollution reduction filters are designed to selectively reduce the transmission of certain wavelengths of light, particularly those produced by artificial light.

The background of the sky is darker and the contrast of emission nebulae is significantly improved. This is the perfect filter for observing nebulae from locations with high light pollution or for increasing the contrast of nebulae from sites with dark skies.
