Former instruments Former instruments at TMO include: • A reflector previously located at
Cloudcroft Observatory was acquired in the late 1980s and became operational in the early 1990s. It was removed from the TMO web site before June 2003. • A
Ritchey-Chrétien reflector built by
RC Optical Systems was attached to an
equatorial mount. It was installed in 2003 and removed from the TMO web site before July 2011. It was housed in the dome where the Schmidt camera was previously located. • A Cassegrain reflector was installed at TMO in 1962.
Harvey Mudd College was the main user of this telescope from the 1970s through at least 1991. • A Cassegrain reflector was installed at TMO in 1966. • A
Schmidt camera owned by JPL operated at TMO from 1985 until at least 1991. • A
millimeter wavelength radio antenna was located at TMO from 1970 until at least 1985. • A radio interferometer with dishes of and became operational at TMO in 1974. == Honours ==
