Columba is a relatively new constellation, having been introduced only in the seventeenth century. It usually is seen to represent the dove that brought back the olive branch to Noah, and that's the way the asterism is shown.
Alpha Columbae is called Phaet, and is a convenient starting point to investigate the rest of the stars here. There are no deep sky objects for binoculars nor double stars of interest to amateur astronomers, but you might want to see if you can pick out the stars that make up the dove, and its olive branch. Also make note that zeta Canis Majoris lies just three degrees north and slightly west of delta Columbae, which forms one end of the olive branch.
