Lee Sang Gak Telescope (LSGT) was installed at the Siding Spring Observatory in 2014 October, and since then, it has been operated through a robotic reservation system, remotely from Korea. This telescope is now being used for educational and research activities of SNU Astronomy program. By placing the telescope at a place with an excellent astro-climate in Australia, the observation class activity can include objects in the southern hemisphere. The installation of the telescope was made possible from support of the Seoul National University and a generous donation from Professor Sang Gak Lee, a pioneering female astronomer in Korea (Retired from SNU in 2013.)
