EAST – Educational Adaptive-optics Solar Telescope

Abstract For the popularization of science with a better public understanding of solar activities, the Educational Adaptive-optics Solar Tel-escope (EAST) Had been built and located at Shanghai Astronomy Museum on July 2021. The EAST consists of a 65-cm aper-ture solar telescope with a 177-element adaptive optics system and two-channel high resolution imaging systems at the Hα and TiO bands, besides three full disk solar telescopes at Ca K，Hα and TiO bands equipped on the tube of the main telescope. In this paper, the configuration of the EAST is described. Its performance and on-sky observational results are presented. The EAST, to our knowledge, is the most advanced solar telescope for the popularization of science purpose in the world. Due to the excellent performance, the data acquired by the EAST can also be used for the research on the solar physics and space weather prediction.
