In fact the "faulty" view was the cockpit view. You can see that if you "move" a planet to the side of your screen - it will become egg-shaped.
After testing some things it occurs to me that the cockpit camera is the only camera you can effectively change with the cameras.ini . You can technically increase the fovx to 120 and you will get a very strange view where you can see much but where it is nearly impossible to play.
