DDO photometry of the open cluster IC 4756
Journal Article

· Publ. Astron. Soc. Pac.; (United States)
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. 12 references.
