The bran-new MEGASTAR-IIA optical planetarium projector was delivered.
It is equipped with the “GIGAMASK”, ultra-precise star plates capable of projecting approximately 1.2 billion fixed stars that is the largest number in the world, and the “SWING AXIS / Ohira Tech – Gimbal Lock Free Technology”, the world’s first cradle-type four-axis control technology that avoids unnatural movements caused by gimbal lock, a problem that conventional optical planetariums have faced.
In a hybrid system with “StellaDome Pro” digital planetarium from AstroArts, the MEGASTAR-IIA realises a variety of starry sky expressions through the smooth fusion of an unprecedentedly sharp and realistic starry sky from an optical projector and images from a digital projector.
In addition to the optical sun and moon projectors, newly developed XY-type planetary projectors installed on the dome edge has been installed for the first time in Japan. Optical planetary projectors were previously installed in the center of the dome, but with the uniquely developed dome-edge type, the central space can be utilised even more effectively, without putting pressure on the seating space.
Reopen on Thursday 1 December 2022.
