Photometric Uand Istandard sequences in the field of the open cluster NGC 7790 are presented. The intention is to achieve wide ranges in magnitude and colour, making these sequences suitable for calibrating deep CCD photometry. The 84 standard stars extend the BVRsequences of Odewahn et al. ([CITE]) to the near UV and IR, respectively. |
