View of the telescope structure and mirrors through the enclosure opening. The inside of the dome is illuminated to show the opened ventilation vents on the side, one of the two Nasmyth platforms to the left, and the telescope in an inclined position with its primary, secondary and tertiary mirrors. The secondary mirror is seen in reflection on the primary mirror. The back of the secondary mirror shows the small launch telescope which is used to propagate the laser light to form an artificial laser guide star to be used for image correction by TMT’s adaptive optics system.
