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.
