+=== PSF determination ===
+To determine the Point Spread Function (PSF) of the telescope, the PSF camera will be used. The PSF camera has a huge image sensor of 60mm x 60mm and 1MPx. The PSF can be determined in the centre of the camera window or offset the centre. The PSF camera can handle light fluxes on approx. 4 orders of magnitude.

+Maybe the PSF camera might be used for additional ultra fine alignment. On Mini FACT this technique was used once and worked out quiet well in combination with the PSF camera.
+Anyhow this is not necessary when the Bokeh alignment has been performed calm and careful. A blocking shield is used here to block a single mirror to locate the mirror to be fine aligned.
