Here's a cgsphere entry I'm finally happy with. Before submitting it I
thought I'd post it here to see what people thought of it... In the end I
left the monolith out, a) because it was really difficult getting it to
look good, and b) because it didn't really fit with the conjunction of
spheres that this image produces.
Anyway, comments welcome, indeed positively invited.

Nice one Bill!
Good modelling on the ship. Io's atmosphere is fine. Good idea of aligning
Jupiter, Io and the ship.
If I could dare some humble comments:
. Jupiter radiates light (self albedo) and the surface in the shadow
should be more visible.
. I would remove Jupiter's atmosphere (perhaps that would be a mistake
....) and increase a bit the contrast of the surface.
. Like you, I don't see how the monolith could take place.

Great image, Bill!
One thing missing (but don't do it now!): a volcanic plume on Io limb.....

This is very attractive and I hope that it gets lots of votes.

I don't think that Io has any atmosphere dense enough to be visible from
outer space! On http://www.solarviews.org/eng/iomountain.htm I found this:
"In spite of the large volume of gas released through volcanic activity,
Io's atmosphere is extremely thin, less than one millionth as dense as
Earth's atmosphere. Most of the volcanic gas condenses back to the
surface in the form of frost."
See you on www.khyberspace.de !

Thanks for the comments fellas.

I didn't know that, but it makes sense. A small ambient value should take
care of that.

I tried Jupiter without the atmosphere but it didn't look right next to
Io's. I think both bodies should be the same; either with or without
atmosphere. I agree about the contrast on Jupiter's surface, too. Easily
corrected...

Er, yes. Good idea, but a project in itself!

Yes, too true. I didn't think Io had any sort of atmosphere, and Jupiter's
certainly doesn't look like that. I wanted them to look slightly
'Hollywood-y', like film effects. I might try them both without atmosphere
for comparison...

Jupiter only emits in the InfraRed, not the visible spectrum... I wouldn't
add any ambient.

I agree it would look strange (if accurate) to remove the atmosphere from
Jupiter.. maybe you could tone it down a little to make it subtly different
from Io
