Temperatures and luminosities for 13 faint central stars in extended planetary nebulae have been derived and placed on the theoretical log L-log T diagram to infer their masses. Despite the initial expectation of finding predominantly higher-mass central stars, it was found rather that the masses cover almost the entire central star range, from less than 0.55 to about 1.1 solar mass and have a mean value of about 0.64 + or - 0.16 solar mass. This value is not significantly different from the average of 0.58 solar mass typically found for the mass distribution both of planetary nebula central stars and of white dwarfs. 27 refs.
