Cross Ratio of corresponding points of intersection in two pencils.

Rectangle ABCD (sides AB, BC, lengths = p and q), side CD is extended back by length c to point 0. BC is divided into n equal parts and points of division connected to O. Likewise DC is divided into n equal parts and connected to B. I terms of p,q and c what is the crossratio of the hyperbola formed by intersection of corresponding points in pencils vertexed at B and O?
