• open clusters and associations: individual (NGC 6811, NGC 6830)
• techniques: photometric

From uvby - beta photometry of the open clusters NGC 6811 (75 stars), and NGC 6830 (19 stars) we were able to determine membership of the stars to each cluster, and fix the age and reddening for each. Since several short period stars have recently been found, we have carried out a study of these variables.
