                                    CCD narrow-band H-alpha photometry of the Sextans A Local Group dwarf
irregular galaxy is presented. Fourteen H II regions have been recorded.
Their identification charts, H-alpha luminosities and sizes are given,
and their luminosity and size distributions are discussed. Twenty-five
stars with masses between 15 and 30 solar masses, distributed following
the IMF of Sextans A, are enough to produce the ionization observed in
the galaxy.
