I'll see how that might work. Ideally I could turn on only the planets/labels, because I don't want the stars on. I can create a button with the additive Sky command that also turns the stars off. I would also have to make sure to turn the stars back on when going to the night sky. I like that it automatically transitions in sky mode so I don't want to lose that. 

The animation is lovely! Someone must have had fun programming that. :^) 
Is there a command to animate them, or is it only done trough the property slider?
