Eight years ago a program was started at the Vatican Observatory to search for faint emission-line stars close to the galactic plane. Indeed at that time few early type emission stars were known fainter than V = 12. This survey consists in a double program:the search for emission line stars with the Vatican Schmidt using the objective prism and an appropriate combination of plate and filter in order to have a narrow passband around Hα(McCarthy Treanor 1970);and UBVRI photometry at the Mt.

Two more will be published later this year. The Vatican Emission Star Survey(VES) resulted in the discovery of about 1000 new emission-line stars; for 700 of those the photometry is finished.
