Inside the Dome
Image taken from http://www.cfht.hawaii.edu/CFHT/Tour/Summit/summit2.html
This picture was taken inside the dome, looking up - the telescope is the structure with the cone-shaped top in the middle of the picture. At the end of each night, the telescope is pointed straight up and the dome is closed. During the day, technicians might work in the dome - different instruments can be installed to change the way CFHT functions.
