We present deep CCD BV photometry in the central region of the faint open clusters ESO 96-SC04 and ESO 92-SC18. The color magnitude diagrams (CMD) here presented allows us to evaluate the clusters ages. We found an age of 5.0x10⁹yr for ESO 92-SC18 and 0.7x10⁹yr for ESO 96-SC04 on the Padova isochrones scale. Estimates of the reddening are given for both the target clusters and the distances of these objects are substantially revised. We conclude that these clusters belong to the old tail of the thin disk population, they are among the most distant known open clusters from the Sun and lie near the solar circle like the majority of the open clusters.
