This type of blocking filter is also known as a Nebular or ALP (anti-light pollution) or an LPR (Light Pollution Reduction) filter. This particular transmission characteristic allows passage of ionized oxygen and hydrogen lines, but blocks light pollution sky reflectance from mercury and sodium vapor lamps. This UHC Filter from Antares will improve your observation of nebulae and other celestial objects which have emission lines in the ionized oxygen or the ionized hydrogen spectral bands. Also good to use in dark sites when light pollution may not be a problem.
