The design of the S-183 three-channel photographic photometer, intended primarily for broadband photometry of UV-rich stars up to visual magnitude 8 or 12 (depending on the stellar spectrum and on channel efficiency), is described. The S-183 boasts low angular resolution (few minutes of arc) and consists of two instruments: an off-axis telescope imaging a 7 deg x 9 deg field of view, and a Schmidt-Cassegrainian telescope imaging a 5 deg x 7 deg field of view. More than 3000 stars have been recorded at 2574 A, with limiting visual magnitude approaching 12. Thirty-four star fields have been observed with the instrument; these include the Large and Small Magellanic clouds, the nucleus of the Andromeda galaxy, and galactic nebulae in Carina, Orion, and Taurus.
