|Detail||：||The first part of the video and Figure 1a were taken from a spot directly behind the telescope, using a Canon EOS 6D and a 1-minute exposure. The second part of the video and figure 1b show the Subaru Telescope motions from the rear and right sides. This video may cause some viewers discomfort, according to photographer Sean Goebel. 'During the change of the target, the rapid motion might make viewers of this video a bit queasy. Please do not fast-forward the video,' he said.
