The Joe McNally Skylite contains a standard Lastolite 3'6" x 3'6" (1.1m x 1.1m) aluminum frame plus a new ''slide on'' fast mount 2 stop diffuser panel. The Skylite also includes a telescopic crossbar assembly which can support the Skylite frame and up to 4 flash guns on sliding shoe mounts which can be spaced apart or grouped together. The crossbar is fully adjustable so Joe can select the angle of the flash guns and their distance from the diffusion panel. The assembly easily attaches to a standard light stand (not included) making it an extremely versatile shoot through panel for strobists
