Public Notes:

188 x 220 x 96 cm (height, width, depth). This reflecting telescope could be operated in two different optical configurations: the Gregorian and the Newtonian. One uses the eyepiece positioned at one extremity of the tube in the Gregorian setup and the eyepiece placed laterally in the Newtonian setup. These two modes of operation were achieved exchanging the secondary mirror (flat in the Newtonian case and concave in the Gregorian configuration).
