Die Bildverschiebung kommt dadurch zustande, dass beim Kippen des Fernrohres das Prisma ( einen Kreisbogen beschreibt, und dass dabei immer andere Theile des feststehenden Diagrammes der ersten reflectierenden Fläche des Prismas c gegenüber zu stehen kommen. Infolgedessen werden durch die Linse d und das andere Prisma auch immer andere Diagrammtheile in der Fadenkreuxcbene abgebildet, und da beim Kippen des Fern-

The image shift is caused by the fact that when the telescope is tilted the prism (describes an arc of a circle, and that other parts of the fixed diagram always come to face the first reflecting surface of the prism c. As a result, the lens d and the other prism always other parts of the diagram are shown in the crosshair plane, and since when the remote
