There is no CGI in this film. Computers were only used for compositing layers of practical effects like classically built models and miniatures (spaceship, spacestation, etc.), holes in black cardboard (stars), color shapes in a water tank (clouds and space nebulae), pancakes (landscapes and planet surfaces), and Styrofoam formations (rocks and caves).
The ship is located in sector 1138. This may be an intentional reference to George Lucas and his inclusion of 1138 in his films.
