Apache Point Observatory
The Apache Point Observatory (APO; obs. code: 705) is an astronomical observatory located in the Sacramento Mountains in Sunspot, New Mexico, United States, approximately 18 miles (29 km) south of Cloudcroft. The observatory is operated by New Mexico State University (NMSU) and owned by the Astrophysical Research Consortium (ARC). Access to the telescopes and buildings is private and restricted.
The ARC was formed in 1984 with the goal of building the 3.5 m telescope. It originally consisted of five institutions: New Mexico State University, University of Washington, University of Chicago, Princeton University, and Washington State University, some of which have since withdrawn.[citation needed]
Several additional organizations have joined over time: Johns Hopkins University, University of Colorado, University of Virginia, Georgia State University, University of Oklahoma, University of Wyoming, and Brigham Young University. Funding for the 3.5 m and 0.5 m telescopes comes from the consortium members, but funds for the 2.5 m telescope come from a much wider array of sources. The 1.0 m telescope is supported exclusively by NMSU.
The ARC 3.5 m (140 in) telescope is a Ritchey-Chretien reflector on an alt-azimuth mount with instruments attached at several focal points. Construction of the building began in 1985, but full operations of the telescope were delayed until November 1994 due to problems with fabricating the primary mirror. From 1991 until early 1993, the telescope was fitted with a 1.8 m mirror, now located at Rothney Astrophysical Observatory under a cost-sharing agreement.
There are a variety of optical and near-infrared instruments available for the 3.5 m telescope, including:
The 3.5 m telescope is also used by the Apache Point Observatory Lunar Laser-ranging Operation (APOLLO) lunar-ranging project. The APOLLO laser has been operational since October 2005, and routinely accomplishes millimeter-level range accuracy between the Earth and the Moon.
Observations using the 3.5 m telescope can be carried out remotely by observers using TUI, the Telescope User Interface, via the internet.
The SDSS 2.5 m (98 in) telescope is used for the Sloan Digital Sky Survey, and began operating in 2000. It is a Ritchey-Chretien reflector on an alt-azimuth mount housed under a roll-off enclosure. It was designed with an unusually large 3° field of view to better support its primary task of surveying the entire sky.
