Abstract : One of the most important problems in star formation is understanding the origin of the stellar initial mass function (IMF). However, the functional form and the universality of the IMF at a very low-mass regime are still open questions. Berkeley 59 (Be 59), a young cluster at the distance of ~1 kpc, is located at the centre of OB4 stellar association and associated with the Sh2-171 HII region. We study the young stellar content, star formation history and IMF of the cluster towards low-mass end. The deep V and I band observations of the cluster Be 59 with 3.6-m Telescopio Nazionale Galileo are complemented with infra red data from 2MASS, Spitzer/IRAC and WISE. The V/(V-I) colour magnitude diagram manifests a clear pre-main-sequence (PMS) population down to V ~24 ( 0.2 M⊙).
