I know this, but Space Engine is supposed to show the universe the way we perceive it, not the way cameras perceve it. If not the way we perceive, then it's not so immersive.
Sorry guys but I am with enioquedes on this. I mean, I think SpaceEngine should eventually do it's best to get the brightness, lighting, and eye exposure as accurate as possible as perceived as us...AS AN OPTION. The current Auto exposure mode is kinda ok at this, except it doesn't have the limits that we have.
Of course we are only simulating "brightness" with diffraction spikes, but when I play with Space Engine, especially in VR, lots of times I wonder how things really look, rather than how they are being shown to me. Most of the time I can do this, but not always. And obviously I am not talking about going blind, but I do think that things brighter than we can "adjust" to should definitely get completely washed out, and things dimmer than we can perceive should just be black in Auto mode.
As for the things that are illusions in our brain, well yeah, I agree that our brain would also do them in Space Engine if we had great VR and Space Engine was set up right
