Report on the stability of tallescopes

The primary aim of this project was to establish whether it could be considered a tolerable practice to move an occupied tallescope, in a theatre environment, for the task of focussing luminaires. This involves moving along a single lighting bar from which a number of luminaires are suspended, focussing each luminaire in turn, once all lights on this bar have been set-up the same process is repeated on the remaining lighting bars.
