rd_asteroid skybox name?

[Uncuepa]

I am testing a space map but can't find the space sky box's name. I assumed sky_moon_1 or asteroid or space, but no success. Anyone know the name?

According to the decompiled map it actually uses sky_goldrush_01, but isn't meant to be seen.
It has a 3D skybox surrounded by tools/toolsblack with a info_particle_system inside of it set to outerspace_stars01.

You can download the decompiled map from here: http://forums.tf2maps.net/showthread.php?t=5952
