Tachy, a friend of mine, helped me considerably by calculating a star catalog for the year 2994 (when the events of the game take place). Some of the stars experience a considerable drift over the 1000 years - it might not be a very important detail to most players, however it is a nice little detail to have.
Here is a simple comparison between the two starfields (move mouse over the image to see the difference - it is exceedingly small visually!):
The newer year 2994 catalog also contains way more stars - 119,614 total. The older catalog has been truncated to only magnitudes brighter than 9.99, so it only listed 28,593 stars.
The synths sensors are sufficiently sensitive to pick out faint stars, so in the end I plan to include all ~120,000 stars (though in reality less based on performance settings, however it does not seem to be considerable for the particle system).
Here is the video of the star field movement over time and how it blends together with the clouds using the mask shown in an earlier post.
Below are the two starfields in higher resolution. These images can be opened at a higher resolution, if you want to take a closer look.
