Özet

136 stars which were known to be members of the open cluster NGC 752 were observed at the R band with the ROTSE-IIId telescope located at the Turkish National Observatory (TUG) site. The data had been evaluated together with BV and 2MASS photometric data. A new practical method for separating dwarf and giant was described and applied. Evaluating the colour magnitude-diagrams with Padova isochrones revealed for the open cluster NGC 752 a metallicity similar to the Sun and an age of 1.41 +/- 0.20 Gyr. g 2006 WILEY-VCH Verlag GmbH& Co.
