Filt. Bandwidth [nm]: 0.3 Adjustable Attenuation : RECEIVE Adjustable Field of View : Transmit Efficiency : 0.9 Receive Efficiency : 0.7 Date Installed : 1973-03-01 Date Removed : 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. : Transmit Efficiency; ~0.9 : Receiver Efficiency: ~0.7 5.
