    Abstract:
    The discussion of the latitudinal and radial photon motion in the Kerr- de Sitter (KdS) spacetime is examined by using the „Chinese boxes“ technique. Only the case with a positive cosmological constant is considered. The latitudinal motion is discussed by using a new motion constant Q vanishing for motion in the equatorial plane. This will be more comfortable for the next discussion of the photon off-equatorial motion in KdS spacetime. For the radial motion an „effective potential“ governing the photon radial motion is used, circular photon orbits are determined and their stability is discussed.
