Changing the IPD helps, however there is definitely a rendering issue as well. The devs tried to offset that by basically only rendering depth to about 5 m or so in front of your cockpit. The world beyond that is completely flat. This works well in smaller ships, up to the cobra, because you brain will tell you that because you don't have stereo separation while look at distant objects they must be really huge. That being said, the effect breaks entirely in the bigger ships. IF you use a type-7 or type 9 the cockpit is so large that it almost extents to the perceived edge of the depth simulation, so that when you look at the canopy and the stars and objects next to it your brain tells you that infact the object beyond your canopy must be tiny in order to be in the same focal plane.
