Description:
    UBV CCD photometry has been carried out on the heavily reddened
    (A_V_=6.7) Cepheus open cluster NGC 7419. An age of 14+/-2 million yr
    and a distance of 2.3kpc have been derived using the isochrones of
    Maeder. The mass function of the cluster satisfies the Salpeter from
    n(M)~M^-{gamma}^ with {gamma}=2.25. The cluster is dynamically
    relaxed.
