These are VFX paintings or photo composites, made for the Battlestar Galactica 1978 pilot episode "Saga of a Star World". Richard Edlund identified these as original paintings done by Ralph McQuarrie. It's not known for what scene it was supposed to be used (other than the background mountain landscape must be the planet Carillon).
