Sažetak
The first CCD photometric investigation of the open cluster NGC 7296 up to now was performed within the narrow band Delta_a photometric system, which enables us to detect peculiar objects. A deeper investigation of that cluster followed using the standard BVR-Bessel filter set. The age and E(B-V) was determined indipendently to log t = 8.0 +/- 0.1 and 0.15 +/- 0.02 respectively by using Delta_a and broadband photometry. In total five Be/Ae objects and two metal-weak stars showing significant negative Delta_a values as well as one classical chemically peculiar star could be identified within that intermediate age open cluster.
