Abstract
We determine the distance and the age of the open cluster NGC 7419 using accurate photometry and spectroscopy. We analyze spectra for a great number of members; concluding that NGC 7419 has one of the highest Be fractions among Galactic open clusters. We also confirm that the cluster contains five red supergiants but there are no blue supergiants. Both effects may be related to fast rotation, but high Be content and high RSG content do not always go together.
