Takayuki Ohira is creating the next generations of planetarium projectors.

In the past, a conventional planetarium reproduced stars ranging up to magnitude 6~7, about 6,000 to 30,000 stars. Meanwhile, the MEGASTAR-I, which was first announced at the IPS (International Planetarium Society) London Conference in 1998, projected 1.5 million stars (complete model has 1.7 million stars), up to 11th magnitude. It revolutionized the planetarium world.

Later on, new models were born one after another, and the number of projected stars in optical systems scores at most 22 million, and expanded to theoretically infinite by using the MEGASTAR-FUSION system which is a fusion of optomechanical and digital projections.

About the project: Star Cave

Galileo Galilei Planetarium (Argentina)

Located in the park near Lake Palermo in Buenos Aires. The planetarium was built in 1966 and has a huge 20 meter dome with a distinctive shape and wonderful light up in the night. The renovated planetarium reopened its doors in 2012. The new system is a hybrid system combining realistic and rich sky of Megastar-IIA with versatile features of Digital Sky by Sky-Skan (USA). This project became the first Ohira Tech’s installation in South America.
