Above you can see a render from the Space Demo Scene.

The scene contains a starfield projected onto a sphere.

Diameter 190km.

The starfield is generated by Vue.

The reason this sphere is so big is because this will prevent cutting haze and fog off or bleeding into fog and haze (at least when Spectral Atmosphere is used)

 

The camera is placed somewhere near the center of the stars sphere.

Focal 66mm. This minimizes distortion near the edges.

 

There are 3 additional sky elements which are in fact pictures mapped onto Alpha Planes. The planes have "Billboard" checked so they will always face the camera.

 

As a reference I also have added a ground plane as well as a terrain which is placed

80km away from the center (hidden when you load the scene)
