I vote for this topic too!
I don’t believe they are, on the contrary and here is why:
-
FS2020 is using a texture projected on a dome.
.
It is clear you can’t have enough pixels in the projected texture otherwise it will be massive a texture size. This approach to night stars is typical to games. -
Because it is a texture it doesn’t take in account magnitude either.
.
In a simulator like X-Plane stars are point lights and the magnitude is simulated as well, so that you only see what you’d see IRL depending on the ambient luminosity too… To each his own.
For those wondering, and Asobo, the XP11 file with the data is plain text:
X-Plane11\Resources\default data\earth_astro.data
It has about 25000 stars in the form:
Ascension Declination Magnitude [name]
The file starts like this:

You can even edit this file in any text editor and add your own geometric figures… I never thought about this one until now
