Here are two STC files to test.
The first file places 50 000 stars everywhere in M31 with a slight increase in density near the central core. The second file places 25 000 stars in the galactic core (some K stars are very big there). The user can easily edit the files to change the star name prefix to his/her taste ("And", "And_C" for Andromeda and Andromeda_Core, so its easy to find in Celestia). Note that the spectral type is given in the name (letter O, B, A, F, G, K, M, followed by a first digit. Other digits are just random crap).http://fsgregs.startlogic.com/Public_Fi ... 1stars.zip
To see more easily some parts of the distribution, I suggest that you use the scaled-disk
option for the stars rendering. However, don't forget that you'll only see the more luminous stars (mostly blue O type). Most stars aren't visible at all if you're too far away.
Also, keep in mind that 75 000 stars scattered in a large spiral galaxy of the size of M31 is really poor, so stars density is extremely low (about typically 700 LY between adjacent stars, on average).
The stars labels are behaving very well, even when the star brightness rendering is pushed to the max (thanks to the low density of stars !). Try also turning OFF the galaxy rendering... To find any G2 stars, just type "And G2..." or "And_C G2..." in Celestia.
Please, I need feedback to improve that stuff. Any crittics, suggestions, comments ?
Let me know if you ever find some weirdness...
