High accurate photometric data in the three filter, narrow-band
-system for five open clusters
(NGC 2489, NGC 2567, NGC 2658, NGC 5281 and NGC 6208) are presented
permitting one
to detect apparent chemically peculiar stars. The ages and distances
are wide spread to improve the statistics of peculiar stars in
our Milky Way. A total of 235 stars within these clusters have been observed.
We have detected ten apparent peculiar objects
(six with significant positive and four with negative -values) in four
open clusters. Although three of them within the boundaries of
NGC 2567 are probably not members of this cluster.
Since no Strömgren 
data are available from the literature,
Johnson UBV photometry was used to test and calibrate our photometric data.
The results from a comparison of both systems are excellent.
Key words: stars: chemically peculiar / stars: early-type / techniques: photometric / open clusters and associations: general
