Happy Jack is an unincorporated community and campground located in the Mogollon Rim Region of Coconino County, Arizona, United States. The Lowell Discovery Telescope is located there.
The Lowell Discovery Telescope formerly known as the Discovery Channel Telescope (DCT), rises seven stories above its foundation. Lowell Observatory owns and operates the 4.3 meter (170 inch) diameter telescope, which is one of the most powerful in the world, thanks to a unique housing that can accommodate up to five instruments at the Ritchey-Chrétien focus. The LDT can switch between any of these instruments in about a minute, making it uniquely suited for time-domain programs as well as opportunity targets such as gamma ray bursts and supernovae.
