FSX / P3D

FSX Modified Star Catalog

A streamlined star catalog sharpens the night sky in FSX while lowering rendering load by limiting entries to magnitude 5.50, trimming the database to roughly 2,900 stars for smoother performance. It also adds ephemeris-style data for Mars, Mercury, Jupiter, Saturn, and Venus to improve planetary visibility and navigation realism.

Shows stars down to magnitude 5.50 to reduce load (about 2900 instead of 9000+). Original idea from J. Chuang. By F. Ronchi.

Added planets data for Mars, Mercury, Jupiter, Saturn and Venus. Unknown source, thanks to the author anyway. All I did was sort stars by their magnitude order then add data for planets.

  • First, backup your original file:
    "Driver"\"FSX install folder"\stars.dat
  • Then replace it with the one I provide in this zip.

That's all.

How to install this mod

FSX / P3D add-on

  1. Extract the downloaded archive

    Use 7-Zip (free) or WinRAR to extract the ZIP to a temporary folder. Don't install while still zipped — the simulator can't read inside ZIP files.

  2. Place files per the readme

    Most FSX add-ons go into one of: SimObjects\Airplanes\, Addon Scenery\, Effects\, or Gauges\.

  3. Always read the included readme

    Every mod ships with a readme.txt or README file. It tells you exactly where files go, what dependencies are needed, and any quirks specific to this add-on.
Still stuck? The readme included with the file is the authoritative source for this specific mod. Visit our Flight School tutorials or ask in our Q&A forum.
