CELESTRON LIGHT POLLUTION IMAGING FILTER RASA 8 EQ8 Each filter is optically polishedThe Celestron Light Pollution imaging filter for the RASA 8" allows high transmission of light from emission nebulae while blocking light pollution, helping to make your images pop with detail off the black sky background with superior contrast. Fortunately, many sources of light pollution have relatively discreet emission spectra; they emit primarily at specific wavelengths of light. By strategically blocking these bad wavelengths, the filter
