    <description>The 2.24-meter Cassegrain/Coudé reflector, also known as the University of Hawaiʻi 88-inch (UH88) telescope, is situated at the Mauna Kea Observatory in Hawaii. Operational since 1970, it was among the first professional telescopes to be computer-controlled, supporting NASA's planetary missions. Notably, it facilitated the discovery of 15760 Albion, the first known Kuiper Belt Object, and numerous outer solar system moons. The telescope's dual Cassegrain and Coudé foci enable versatile observational capabilities, supporting a broad range of astronomical research. </description>
