摘要：

The results of astrometric and photometric investigations of the open cluster NGC7243 are presented. Proper motions of 2165 stars with root-mean-square error of 1.1 mas yr(-1) were obtained by means of PDS scanning of astrometric plates covering 97 years. A total of 211 cluster members down to V = 15.5 mag have been identified. V and B magnitudes have been determined for 2118 and 2110 stars respectively. Estimations of mass (348 M-. less than or equal to M-TOT less than or equal to 522 M-.), age (t = 2.5 x 10(8) yr), distance (r = 698 pc) and reddening (EB-V = 0.24) of the cluster NGC7243 have been made.
