    Default Nebular filters and the Emission Lines



    Hello all,

    as the nebular filters and the emission lines in DSOs become increasingly an important FAQ, find below a founded analysis with pictures of the emission line spectra, and on the nebular filters,

    Nebelfilter

    as investigated by Sven Wienstein. The page is in German, but you can possibly run a translator on it. The pictures and graphics included are self-explanatory, and highly interesting, including new insights.

    Hopint to have helped
