A search of emission stars has been done on the basis of digitized photographic plates received with the 40″ Schmidt telescope of Byurakan Observatory equipped with a 4° objective prism. Forty-six new emission stars are found in a small area around the known FU Ori type variable V 733 Cep. Emission stars on the J - H - H - K diagram are situated on or in the neighborhood of T Tau locus. V, R, I photometry for some of the emission stars is performed as well. Three new variable stars are found in the region. A rapid brightness variation is detected on V 733 Cep.
