Abstract
ABSTRACT DDO photometry is presented for 13 red stars in the field of IC 4756, ten of which are classified as proper-motion cluster giants. Of these ten, one is found to be a dwarf, in agreement with the uvby photometry of Schmidt (1978). The strength of the delta CN cyanogen excess parameter for five of the giants indicates that the cluster has essentially solar abundance.
