dc.description.abstractThe open cluster NGC 2818 containing a planetary nebula has been observed in VRI bands using the CCD system at prime focus of the 2.3 meter Vainu Bappu Telescope. The study extending to stars V of 21 magnitude established the distance modulus as (m - M)0 = 12.9 + or - 0.1 for the cluster. Based on the fitting of theoretical isochrones computed for solar metallicity, an age of 5(+ or - 1) x 10 to the 8th years has been assigned to the cluster. Association of the planetary nebula with the cluster indicates that the progenitor mass of the planetary nebula on the main sequence is at least 2.5 M solar masses.en
