Our Projects
T60
T60
In September 2014, we opened the T60 observation facility, a telescope dedicated to observing planetary atmospheres. Located at the 3,000-m summit of Haleakalā on Maui, Hawai‘i, this site hosts a cluster of world-class facilities. In collaboration with the University of Hawai‘i, we operate the 60 cm optical telescope T60, equipped with three unique instruments for cutting-edge observations of Solar-System bodies and other targets.
60cm望遠鏡の諸元
| 有効開口径 | 600mm |
| 焦点距離 | 7200mm / (カセグレン焦点) 14400mm (クーデ焦点、現在は不使用) |
| 視野 | 最大10’（観測装置によって異なる） |
Visible Adaptive Optics
Ground-based images normally shimmer in the turbulent atmosphere. Our visible-wavelength adaptive-optics system corrects these distortions in real time, delivering diffraction-limited clarity. The left image compares Mercury observed with and without AO during daylight.
Visible High-Resolution Spectrograph
A fiber-fed echelle spectrograph with 120 fibers achieves a resolving power of R ≈ 65,000 in the visible. It probes planetary atmospheres, ionospheres, and magnetospheric gases with unprecedented detail.
DMD coronagraph
Designed to capture the faint plasma glow around Jupiter originating from Io’s volcanic gases (see left image), this coronagraph employs a Digital Micromirror Device (DMD) to block the overwhelming glare of Jupiter and its moons.

High-precision Polarimeter Dipol2
Built by the University of Turku, Dipol-2 performs spectro-polarimetry with a remarkable 0.001 % accuracy
Near-Infrared Spectrograph ESPRIT
Currently under development.
