Abstract:
    Hβ photometry is given for 263 reddened and very reddened stars
    from the Stephenson & Sanduleak (1971, Cat. III/43) catalogue of
    Luminous Stars in the Southern Milky Way (LSS). The results are
    combined with the uvby photometry presented in Paper I to determine
    reddenings, E(b-y), and distances for the stars and to estimate the
    spectral types and luminosity classes from derived Teff and MV
    values.
