Sight alignment indicia on a sphere being indicia made on opposing sides of a sphere, the indicia positioned from about 0 degrees to 23 degrees north of the equator of the sphere, and visible at the same time to one standing over the ball. A sphere surface template marking device comprising a shell having an outer-surface and inner-surface generally defining a hemi-spherical portion of a sphere adapted for receiving a portion of the sphere so that the inner-surface substantially conforms thereto, the shell having an edge portion approximating the equator of the sphere, at least two grooves disposed there through, with the grooves positioned on opposing sides of said shell from about 0 degrees to 23 degrees north of the edge portions of the sphere, serving to receive and guide a marker imprinting indicia on said surface of said sphere.
