The Okayama Astrophysical Observatory 188-cm reflector telescope primary mirror realuminization project has long been one of the signs of early summer in Okayama Prefecture. The staff involved in the realuminization works has changed greatly over the course of the more than 50 years since it started in 1960. But, this time like always, there is the commitment to accomplish the project safely and the perseverance to face the task of making the mirror sparkle for another year. This is what supports Okayama Astrophysical Observatory's shared use.
