The scene consists of three elements: a vacuum defined by a perfect sphere of 1e140 meters, the sun (with a spectrographic extra-atmospheric emission spectrum), and a camera modeled with a Canon 24mm objective.
The Canon 24mm objective consists of 13 lenses (traced from an internet diagram) + 13 overlapping lenses a few nanometers larger that serve as an anti-reflective coating, so that a film of constant thickness remains around each lens. By means of precedence, the lenses remove the excess of the coatings (the higher the precedence between bodies with mediums, the lower the precedence is evacuated. In this way, a very thin film remains around the lenses that form the coating). Then we have the body of the objective and the camera (functional, without details), a volume of ozone that covers the lenses and coatings (an interlens pressurized gas), the eight-blades diaphragm and finally the film, at the correct convergence distance of focus.
We thus have a series of coating-lens-coating-ozone mediums (x13), 52 mediums. An orthographic camera (without perspective) captures the image that is formed on the film. It is played with the movement of the lens groups and the F-stop to achieve the desired focus.
The camera is located at the distance between the sun and the Earth. It's about getting physical lens flares.
In the image the plan of the engine of the Holy Spirit is drawn with light, hence the name of this Synthetic Photography. This type of optical exercises leaves a homogeneous grain that resembles the chemical grain of analog films.
