Object name: NGC2194
NGC 2194 is an open cluster just east of Orion's club about 12,000 light years away. That makes it 35 to 46 light-years in diameter depending on whose size measurement you use. As open clusters go this one is rather old at about 325 million years of age. This likely accounts for the numerous red giant (actually orange) stars seen in the cluster. The cluster is lightly reddened by 0.38 magnitudes. That isn't enough to account for these red stars.
