This picture shows around Castor's feet, an older brother of Gemini. You can see M35 (NGC2168) with medium-sized diameter. This is an open cluster easily enjoyed in small scopes, extremely attractive, with curving series of glittering stars. Several hundred of stars are contained in the cluster, which is about 2600 light-years away.
Another small cluster can be detected at just SW of M35, it's NGC2158. The cluster is characteristic because many reddish stars are included in that, about 15 thousand light years away.
