Set direction spread to 0. Ramp the particle opacity so that the stars fade in and out over their = life. Place the emitter far enough away from the camera so that no particles = get too close before they fade out. Add the spherical field to the camera's position in case any particles = get near enough that you need it. Then tweak it to get the motion you want. It works for me. Like flying through a star field without moving the = camera.

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.
