How do I create a star field camera fly-through, which does not "get bigger" like this (video) ...?

I’d like to create a starfield (actually not stars but rather space dust/debris) like the video below.
But when particles come towards the camera they generally get bigger.
Is there a way of making sure the stars don’t get bigger and blur / pixelate? I’d rather animate the particles than the camera if possible.

Maybe you can change particle size over time…

You can make particles disappear before they get close to camera

thanks, but if the stars disappear as they approach the camera, its not realistic.
