CCD photometry of distant open clusters NGC 2425, Haffner 10 and Czernik   29
  We present BVI photometry for poorly known southern hemisphere open clusters: NGC 2425, Haffner 10 and Czernik 29. We have calculated the density profile and established the number of stars in each cluster. The colour-magnitude diagrams of the objects show a well-defined main sequence. However, the red giant clump is present only in NGC 2425 and Haffner 10. For these two clusters we estimated the age as 2.5 +/- 0.5 Gyr assuming metallicity of Z=0.008. The apparent distance moduli are in the ranges 13.2<(m-M)_V<13.6 and 14.3<(m-M)_V<14.7, while heliocentric distances are estimated to be 2.9<d<3.8 kpc and 3.1<d<4.3 kpc, respectively for NGC 2425 and Haffner 10. The angular separation of 2.4 deg (150 pc at mean distance) may indicate a common origin of the two clusters.
