UHC is short for Ultra High Contrast, a broadband filter with an obvious effect on blocking city harmful lights.
UHC filter blocks lights selectively, especially the mercury and sodium light
from manmade lamps and the skyglow in nature.
UHC filter lets the light from nebula highly transmit, it has a high
transmittance at the region of OIII(496nm & 500nm), Hβ(486nm),
NII(654nm &658nm), Ha(656nm)and SII(672nm).
Our UHC with higheffectively improved the contrast of the nebula,
ensuring wonderful nebula details.
