NGC 225 - Open Cluster in Constellation Cassiopeia

NGC 225 is an open cluster in the constellation Cassiopeia. It is located roughly 2,200 light-years from Earth. It is about 100 to 150 million years old. The binary fraction, or the fraction of stars that are multiple stars, is 0.52. It is also known as sailboat cluster. But what's happening at the top of the mast? The boat is obviously being boarded by an octopus - the more clearer, the longer you expose (or if you drink too much red wine)... Beside the quite nice, probably not so well known star cluster you can see interesting dust clouds and a reflection nebula, which are cataloged as LDN 1291 and LBN 604.
