Facilities
– Prime-focus optics with four wide-field correct lens
– Fork-type equatorial mount
– Delivered image quality of less than 1.0 arcsec
(Under the atmospheric seeing of 0.75 arcsec)
– Optical performance optimized in the I-band
– Drawer-style filter changer to mount four filters
(Johnson-Cousins BVRI)
– Sliding shutter with rectangular blades
– Dome of 9.2 m in diameter from ASH-DOME

– 0.40 arcsec per pixel, 2.0 by 2.0 square degree FOV
– Quantum efficiency of ~85% in V and ~80% in I-band
– Readout time of 30 seconds with 32 readout channels
(Overhead time to take one image is about 90 seconds)
