Abstract
CCD and photoelectric UBV photometry are presented for 32 stars in the nuclear and coronal regions of NGC 6823 and for 13 stars in its central trapezium system. The stars in the inner and outer regions of the cluster exhibit a wide range in their derived color excesses, while the computed reddenings for the trapezium stars are found to be very similar. Photometric data for 36 field stars towards the cluster indicates that about 0.6 mag of absorption is due to foreground interstellar material. From near-IR photometry, the reddening law is found to be uniform across the cluster and is characterized by R V = 3.2.
