The Hyper Suprime-Cam

The Hyper Suprime-Cam (HSC) is a gigantic mosaic CCD camera, which is installed at the prime focus of the Subaru Telescope. The HSC uses 104 main science CCDs, which cover 1.5 deg FoV in diameter, with a pixel scale of 0.17", as well as 4 CCDs for auto guider, and 8 CCDs for focus monitoring. Information about the instrument can be found at:
We recommend to read the instrument information above first. For each observing run a set of filters is defined, and observations are performed in these filters only. Due to the construction of the instrument, changing filters during the night is time-consuming and is not done frequently.

Questions regarding HSC should be directed to Drs. Satoshi Miyazaki (satoshi [at], Fumiaki Nakata (nakata [at] and/or Tsuyoshi Terai (terai [at]
