In ZT Metal Kralovice under the supervision of Mr. Cepek we have started construction of the Quadruple telescope, see the attached drawing. This step is bringing us closer to the final opening of our observatory for the public and education. The dome of the observatory has extraordinary parameters, when compared with the usual astronomical observatory. Main difference is in the ability of the dome of very fast rotation. The dome must be able to change the position to any location on the sky within the 20 sec. The reason is, that the telescope is intended for the registration of the short living Cerenkov radiation. On the attached picture you may see the view of the Quadruple telescope, upper part, and the rotating base (on the right). Red spots in the picture are indicating CCD detectors.
