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.
