Kyoto University 3.8-m Telescope project at Okayama


Title: Kyoto University 3.8-m Telescope project at Okayama
Speaker: Tetsuya Nagata
Date: Thursday, 20 March 2014
Time: 11:00 - 12:00
Venue: SAAO Auditorium


Kyoto University has been constructing a 3.8-m telescope of 18 petal-shaped segment mirrors, with an ultra-light-weight mounting; the mirrors are produced with high-precision grinding. It is to be located at the Okayama Astrophysical Observatory (of National Astronomical Observatory, Japan) site, where a younger 1.88-m telescope (than the one at Sutherland) was placed in 1960. Its main objectives are time-domain astronomy and direct imaging of exo-planets with extreme adaptive optics.

We launched the project in 2006, and a variety of technical developments have been executed since then, on a private fund. The upper part of the ultra-light-weight mounting was constructed in 2010; some of you might have seen it in the “10 years of IRSF” conference at Nagoya University. We have succeeded this year in getting government budget for the completion of the telescope. The configuration construction is completed in 2015. It is to be the hub of the seven-university collaboration “OISTER (Optical and Infrared Synergetic Telescopes for Education and Research)”, which IRSF belongs to, and will be opened for the astronomers over Japan, and the world, in 2018.
