The optical appearance of an electrically charged stellar core when an indefinite collapse leads either to formation or nonformation of a black hole is discussed. The motion of photons in the Reissner-Nordstrom field is analyzed, and the brightness and redshift are calculated. When the charge Q is less than the mass M, the collapse ends in charged black hole, and the phenomenon is qualitatively similar to the uncharged case, i.e., an exponentially increasing redshift and an exponentially decreasing intensity, but the time constant may be very much greater. If Q is larger than M, the collapse ends in a singularity, and infinite redshift and vanishing of light will be seen optically within a finite time. But the formation of a singularity does not seem to be possible; more probably, a steady, vibrating configuration will form which will show a very large redshift if Q is close to M.
