Abstract The faint cluster, King 8 (IAU designation C00546+336), was observed as part of a study of galactic anticenter stars, which are used as probes of the environmental conditions in the outer galactic disk. The distribution of stellar ages and metallicities as a function of position can be compared to the properties of solar neighborhood stars, and thereby serve as constraints for theoretical models. BV observations are considered, taking into account photoelectric data, photographic data, and video camera data. The final photographic values for all stars measured are listed in a table. Video camera magnitudes were averaged with photographic magnitudes when available. Attention is given to a color-magnitude diagram, the luminosity function, a two-color diagram, slitless spectra, and IIDS spectrophotometry. The color-magnitude diagram morphology of King 8 suggests this open cluster is a moderate age, 800 million years, metal-poor (Y = 0.30, Z = 0.01) object located in the anticenter 3-4 kpc from the sun.
