UHC Filter 1.25 inch/2 inch/EOS-C for reducing light pollution in astronomical photography

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 sources.

The background of the sky is darker, and the contrast of emission nebulae is significantly enhanced. This filter is perfect for observing nebulae from light-polluted sites or for increasing the contrast of nebulae from dark sites.

Due to its ability to produce exceptionally sharp and clear images, this UHC filter is considered one of the most popular accessories in astronomy. It can be used not only for celestial observations but also for astronomical photography.
