Scientific paper

We present deep Halpha+[N II] CCD images of selected new Planetary Nebulae (PNe) discovered through an [O III] 5007 A emission line survey in the Galactic Bulge region with l > 0 deg. In total, we detected more than 200 objects, including 45 new PNe. Deep Halpha+[N II] CCD images as well as low resolution spectra were obtained for the new PNe in order to study them in detail. Their first morphological study suggests that most of them are round (60%), while 31% and 9% are elliptical and bipolar, respectively. 63% of the round PNe present ring-like structure while 37% are compact.
