Designed to better enable nighttime viewing of nebulae through telescopes featuring a 2"-diameter eyepiece, the UHC Nebula Filter from Explore Scientific increases viewing contrast by blocking a majority of the wavelengths of light pollution in order to gain increased detail. This filter passes the H-Alpha and H-Beta emission lines at 486nm and 656nm, as well as oxygen emission lines at 496nm and 501nm, in order to brighten nebulae while darkening the sky background for increased contrast and subject definition. Compared to unfiltered observation, this UHC filter offers clear visibility of the Owl Nebula M97, Veil Nebula NGC6992, and even the Dumbbell Nebula M27 when observing under typical terrestrial lighting.
