Abstract
A new CCD color magnitude diagram (CMD) for the intermediate age open cluster NGC 1245 is presented. The cluster appears to be rich, but loo se, irregular and very broad. Adopting the metallicity value of [Fe/H] = +0.14 from Lynga (1987) we obtain a color excess E(B-V) = 0.26, an apparent distance modulus (m - M) = 13.20, and an age of 8.0 x 10(8) y r. This puts NGC 1245 at a distance of about 3.0 Kpc from the Sun. The analysis of the CMD shows the presence of various field populations, and some evidences of differential absorption.
