       Additional Information     : The telescope is a fixed, north 
                                  : facing refractor. There is a flat pointing
                                  : mirror (or beam director) that is mounted 
                                  : in a gimbal that is positioned in both
                                  : axes (Az/El). The flat mirror is the
                                  : coelostat. This configuration is like no
                                  : other telescope in the network. It is not
                                  : really a coelostat either since they usually
                                  : have two flat mirrors with the coelostat 
                                  : mirror fixed in one axis.
                                  : That is why this device was named the 
                                  : lunastat by the folks who built this 
                                  : observatory. It has different properties from
                                  : telescopes mounted in AZ/EL or X/Y mounts.
                                  : The most important difference is that there
                                  : are no problems tracking through zenith.
                                  : Our tracking difficulties happen when we are
                                  : pointing low in the north. The flat mirror
                                  : is in a AZ-EL mount. But that is not our
                                  : telescope. Its just a flat reflecting mirror.
                                  : The telescope is in a fixed mount.
