The way I figure it, distances between the stars are massive so even though we are flying at massive speeds through a star field we would not see a star at more than a few pixels size unless we're actually REALLY close to it. So what I'm trying to achieve is a fly-through where we never actually get that close to individual stars but we do have the sense that we're moving through the star field. If I set things up in such a way that the closest stars are relatively small, then the distant stars disappear altogether.
