bug with brown dwarf

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)
[/edit]
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?
