Kilodegree Extremely Little Telescope

KELT consists of two telescopes, KELT-North in Arizona in the United States, and KELT-South at the SAAO observing station near Sutherland, South Africa. Each KELT telescope consists of a wide field (26 degrees × 26 degrees) medium format telephoto lens with a 4.2 cm aperture, mounted in front of a 4k × 4k Apogee CCD. Each can also be equipped with an alternative narrower field (10.8 degrees × 10.8 degrees) lens with a 7.1 cm aperture for a narrow angle campaign mode. KELT-North uses an Apogee AP16E camera, while KELT South uses an Apogee U16M. The optical assemblies and cameras are mounted on Paramount ME mounts manufactured by Software Bisque. The telescopes were made with off-the-shelf components, and were thus much cheaper than many observatories. • KELT-North is located at Winer Observatory in southeastern Arizona, about an hour's drive from Tucson. KELT-North was installed at Winer in 2005, and operated continuously until 2022, with occasional interruptions for equipment failures and poor weather. KELT-North was decommissioned in 2022. • KELT-South is located at the Sutherland astronomical observation station owned and operated by SAAO, about 370 kilometers (230 mi) North of Cape Town. KELT-South was deployed at Sutherland in 2009.
