A few foils of the MagicBlack (Acktar Ltd) black optical coating have arrived to Moreno-Pujal. This innovative material shows an hemispherical reflectance below 1.8% even in a broader spectral range than the one required by the Baker-Nunn system.

 MagicBlack will shortly be installed in the internal walls of the CCD housing which are close to focal plane. This way, the internal reflections which yield to ghosts images of bright stars, which are always a concern in very fast systems as the f/1 Baker-Nunn, will be minimized.
