As the observatory's first telescope, it has played a pivotal role in various astronomical studies, including the initial phase of the Optical Gravitational Lensing Experiment (OGLE) in 1992 . The telescope has also been instrumental in projects like the Cluster AgeS Experiment (CASE), which investigates the ages and distances of globular clusters through observations of eclipsing binaries . In 2017, the Swope Telescope contributed to the discovery of SSS17a, the optical counterpart to the gravitational wave event GW170817.
