Abstract
Improvements are disclosed to lighting fixtures, support structures, interconnecting cabling, and other subjects. An improved method allows precise control of the beams of high power, long throw followspots by means of a steering mirror motorized in two axes. The beam is first directed upwards from the followspot by a first mirror to the steering mirror above. The range of elevations through which the beam can be steered is increased by displacing the steering mirror relative to the first mirror such that the portion of the beam between them is not vertical.
