Objective prism spectral types and photographic U, B, V magnitudes have been determined for 1810 stars in a region of 19.5 square degrees of Cepheus centered on the galactic cluster NGC 7160. A catalogue of data together with identification charts is given. The magnitude limit is approximately V= 12.5. The field contains a part of the supposed older subsystem of the association Cepheus OB2. The interstellar absorption in the region is smooth. The visual absorption is 1.0 mag. at the distance of the association for the northern part of the field, and is about 1.4 mag. for the southern part. Space densities of the stars have been computed as a function of spectral type and distance from the sun. Concentrations of B and early A type stars are found at 800 pc from the sun. Concentrations of B and early A type stars are found at 800 pc, and an attempt was made to derive the shape of the luminosity function of the association subgroup.
