This image was produced as a composition of independently integrated sky and foreground layers, using the image sequence featured at the beginning of "Oasis de Oscuridad" timelapse, with the Big Dipper taking a spoonful of the ground. This startrail composition itself is blended with the timelapse at the end of the opening clip.
