A search for new objects in the transition phase between AGB-stars and planetary nebulae
Preliminary results are presented from a spectroscopy survey of IRAS sources with colors similar to those of planetary nebulae. Two new planetary nebulae, some H-alpha emission line stars, one peculiar source which is probably a premain-sequence object and a new Seyfert I galaxy have been found.
