Abstract:
    This paper is dealing with the investigation of H-alpha emission stars
    towards the galactic bulge. In this important region 533 H-alpha
    emission stars have already been discovered. We add 98 new and 9
    possible new (perhaps identical with known objects) H-alpha emission
    stars found in the objective-prism survey of planetary nebulae and we
    give the identification charts, the accurate coordinates as well as a
    rough description. The distribution in l, b of all objects shows the
    expected concentration towards the galactic equator with the maximum
    near l=0 and b=0 distorted probably due to strong interstellar
    extinction.

Note (1): The intensity of the main emission lines was estimated in a
     relative scale: 1=faint,...,5=very strong or over-exposed
Note (2): The continuous spectrum was described as follows:
     -  = no continuum observed or continuum extremely faint
     a = faint continuum
     b = continuum of medium intensity
     c = strong continuum
     d = very strong or overexposed continuum
Note (3): Remarks as follows:
     -  = not visible
     bl = blend
     em = further emissions
   Hvar = H-alpha variable
    Var = variable
     no = no plate


Global notes:

Note (G1): The letter S (suspected) added to the name expresses
       a) our doubts mainly concerning the reality of the H-alpha emission
          line which means its possible confusion with another emission line;
       b) the very small contrast of the line with regard to the continuum
          or its faintness;
       c) our doubts about the star-like appearance of the object.
