Scientific paper

The KPNO Video Camera system has been used to determine main-sequence color-magnitude diagrams for the metal-rich globular cluster NGC 6171 and the metal-poor cluster M3. Comparisons with theoretical isochrones and considerations of the magnitude difference between the horizontal branch and the turnoff both indicate that the ages of these clusters are identical to within the uncertainties of the determinations. If (m - M)v + 14.80, Fe/H = -0.9, and E(B - V) = 0.38, then the age of NGC 6171 is 16 + or - 3 Gyr for a helium abundance Y = 0.24.
