Filt. Bandwidth [nm]: 0.3 Adjustable Attenuation : RECEIVE Transmit Efficiency : ~0.9 Receive Efficiency : ~0.7 Date Installed : 1973-03-01 Date Removed : (yyyy-mm-dd) 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. Back to top 5.
