Push-To Telescope Mathematics
Teets, Donald
College Mathematics Journal, v43 n3 p227-231 May 2012
Two coordinate systems are related here, one defined by the earth's equator and north pole, the other by the orientation of a telescope at some location on the surface of the earth. Applying an interesting though somewhat obscure property of orthogonal matrices and using the cross-product simplifies this relationship, revealing that a surprisingly small amount of information is needed for the telescope controller to locate objects in the night sky.
