Jovian Moon Immersed in Jupiter's Shadow Always Glows at Wider Fields of View

Jupiter's moon Io, when going out of immersion from Jupiter's shadow, should wink on from darkness and does so at narrow fields of view. At expanded/realistic fields of view such that more of the moons of Jupiter are visible, then they all glow, even immersed Io.

Is that a feature? Is it something I can disable?

When a moon (or any object) is too far away to be resolved, Celestia displays a white dot at the position of the moon so you can see it.
I'm not sure if this is something that can be disabled.

A way to disable it

Set the Io part of .../<CelestiaDir>/data/solarsys.ssc to:

Code: Select all

"Io" "Sol/Jupiter" {
  ...
  Albedo 0 # No albedo
  Color [ 0 0 0 ] # Black dot color
  BlendTexture false # Avoid to paint the texture with the above color
  ...
}


It's possible for all objects
