In professional theatre,
auditoriums,
arenas, amphitheaters,
performing arts centers. community and school theaters, spot operators may use a
reflector sight. The reflector sight is attached to the followspot, allowing the operator to align the follow spot more accurately. The operator, when looking through a Telrad, will see multiple red rings which may be dimmed to assist in low lighting. Often times the placement location's distance and alignment of the sight's housing unit on the spotlight, in relation to the operator's eyes, will allow the rings to align with the standard sizes of head illumination, half body illumination, and full body illumination. The various distances of spot light location set up positioning based on the venue's size and the spot locations may also affect the need for devices to assist in aiming. ==See also==
