The Discovery Channel Telescope (DCT) is a 4.3 m (170 in) aperture telescope built by Lowell Observatory and The Discovery Channel.[1][2] DCT was built at a dark sky site in the Coconino National Forest near Happy Jack, Arizona.[3] Happy Jack is located at an elevation of 2,360 m (7,740 ft) and is approximately 65 km (40 mi) south-south-east of Flagstaff. The project was initially a partnership between Discovery Communications and Lowell Observatory. The research partnerships have been extended to include Boston University, The University of Maryland, The University of Toledo, and Northern Arizona University.
