bug with brown dwarf

[Methyl Orange]

I have a weird bug with brown dwarf I've created. It's in orbit 1300 AU around barycenter with a yellow giant star. When I go to the brown dwarf, it simply isn't shown! I can't see it even if I'm on the surface! What's wrong? I have Celestia 1.5.0, Windows Vista and graphic card NVIDIA GeForce 8800 GTS.

Confirmed.
[edit]
This problem is seen with both v1.5.0 final and svn r4230 (current)

Stars dimmer than AbsMag 25 and SemiMajorAxis greater than 1010 AU from the barycenter are not drawn. They should be. Here's a test STC file. The star named "bd" is not drawn. Change the AbsMag to 25 or the SemiMajorAxis to 1000 and it is drawn.

Code: Select all

Barycenter "giant_bd"
{
   RA 1
   Dec 1
   Distance 11.824
}

"bd"
{
   OrbitBarycenter "giant_bd"
   SpectralType "O2III"
   AbsMag 26

   EllipticalOrbit {
      Period       15.5
      SemiMajorAxis   1011
      ArgOfPericenter 0
   }
}
"giant"
{
   OrbitBarycenter "giant_bd"
   SpectralType "O2III"
   AbsMag 1

   EllipticalOrbit {
      Period       15.5
      SemiMajorAxis   10
      ArgOfPericenter 180
   }
}

And what's wrong? Maybe wrong app. magnitude calculation? It appears if I have magnitude limit 11.50, but on mag.limit 11.40 it isn't shown. I think it calculates app. magnitude from distance from barycenter not from star. Am I right?
