Designed to better enable deep sky observation of nebulae through telescopes featuring a 1.25"-diameter eyepiece, the UHC Filter from MrStarGuy enhances viewing contrast by blocking a majority of the wavelengths of light pollution in order to gain increased detail. Constructed from optical glass for consistent viewing clarity, this filter passes the H-Alpha, H-Beta, and O III lines in order to brighten nebulae while darkening the sky background for greater subject definition. The filter is recommended for general use in a variety of viewing conditions.
