A photometrical study of the complete to B = 21m sample of the objects is carried out. Direct photos of the 1 sq. degree field with center coordinates 9h40m + 50° are obtained at the 1-m telescope on mount Majdanak. The complete sample contains 2222 objects. A description of the observations and data reduction is given. The results of the photometrical study are gathered into the catalogue. This complete sample is the basic one for future spectral investigation of the objects.
