Scientific paper

CCD photometric observations of open cluster NGC 7419 in UBVRI passbands have been made down to V = 19.5 mag. Reddening across the cluster region is found to be variable. The mean visual absorption of 5.30 mag and a distance of 2 kpc have been estimated for the cluster. The cluster age has been estimated to be nearly 40 Myr and less than 40 Myr, using the convective core overshooting isochrones and empirical isochrones respectively.
