In Ohira Tech, Takayuki Ohira, the creator of the first professional portable planetarium projector, developed the Megastar Class, which is the first compact and portable opto-mechanical star projector to simulate a full sky starry environment. This was possible due to the use of an ultra-bright LED light source, original metallic star plates manufactured by Ohira Tech, and a fish-eye projection lens.

CLASS is acronym of Compact, Light, Accurate, Simple and Silent.
It projects over one million stars in thier real positions and magnitude, on full dome surface.
It demonstrates diurnal motion of the stars and a special lights effect such as Twilight, blue sky, and other effects.
Megastar Class is optimal to use in private dark space as well as business and show space such as bars, restaurants, spa and other facilities.
