The Open Star Cluster NGC 2194 has a distance of 1600 pc in the direction of the constellation Orion. Most stars of the cluster have a slightly blue color, but there are also a lot of bright and yellow stars. They are evolved, i.e. they already left the usual stage of hydrogen burning in the core. This is a hint for the relativ old age of the cluster. Indeed NGC 2194 is with 109 years about ten times older than the cluster M 50, and so belongs to the unusual population of old Open Clusters in our Galaxy.
