I really like the stars in the sim.
With nVidia cards, you can use the GeForce experience panel and play with the exposure filter in order to see the stars as if each frame had been taken with a very long exposure, it isn’t natural but it is a lot of fun, some expensive color camera can do that IRL (such as the x27 night camera for cinema).
I made a video to demonstrate this feature, the presence of stars is useful in order to add visual references during areobatics:
(sorry for the cheesy free music)
With GeForce experience you can also capture raw HDR screenshots and treat them as you would do with real raw night pictures. It is a great feature for photographers willing to preview a shot or a timelapse at a given location.
Here is an example of what a raw 32 bit capture from the sim can give you:
