Abstract:We present the first results of a spectroscopy survey of iras sources with colours similar to those of planetary nebulae.Two new planetary nebulae, some Hagr emission line stars, one peculiar source which is probably a pre-Main-Sequence object and a new Seyfert I galaxy have been found.Based on observations collected at the European Southern Observatory, La Silla, Chile.
