A sky-limited, red-sensitive IIIaF plate taken of the field of the W50 supernova remnant reveals two areas of nebulosity, 20 arcmin in extent, centered on SS 433 (1909 + 048) and separated from each other by 70 arcmin. Red spectra at high resolution obtained with the Anglo-Australian telescope show strong evidence for excitation by low velocity (40-60 km/s) shocks. From these data and from morphological considerations it is concluded that these optical filaments are excited by the relativistic beams of SS 433 and a mass loss rate in the beams of approximately 3 x 10 to the -6th solar masses/gr is derived by two independant techniques. The age of the system is about 100,000 yr. The data indicate supercritical accretion onto a compact object as the power source of the beams. If this compact object is a black hole it has mass in the range 2-40 solar masses with a probable value of order 12 solar masses.
