The Danish king gave Brahe the Island of Hveen to pursue his work. Without benefit of a telescope, Brahe used armillary spheres that were able to physically represent a model of the sky and develop celestial maps of planetary movement. Brahe created detailed mathematical tables that astronomers used for centuries.
