Non-sidereal tracking with Subaru Telescope

Subaru Telescope is able to perform non-sidereal tracking of Solar System objects. Additional preparation is required, however.

Observers should prepare a file like the following, and send it to either their support astronomer or Tomonori Usuda <usuda at subaru.naoj.org>.

Please follow the detailed instruction to make files by using a software in the Subaru computer system at the summit or transfer them. You need an user account for the system.
