Spinrad, H. ; Stone, R. P. S. Abstract Mattila's (1976) dark-cloud method was used to search for a diffuse extragalactic background component in the optical surface brightness of the night sky near 4000 A. The dark nebula L134 was used as a photometric reference in which the extragalactic background is negligible. L134 was compared with nearby clear regions of sky. No positive detection was obtained; the 1-sigma upper limit is about 2.6 S(10) units = 4 x 10 to the -20th erg/sq cm per sec/sr per Hz (or a B surface brightness of 26.7 mag per sq arcsec). A more conservative 3-sigma limit is about 5 S(10) units. The implications of the present limit and that of Dube et al. (1977) for galaxy evolution and recent counts of faint field galaxies are discussed.
