Thanks!
I'd hoped the sun, at least, would make the case for these
*not* being models, but I suspect that it's reflection in
the table spoils the effect somewhat. I'm not using an area
light but I believe that only affects shadows anyway.
As I'm aiming towards making the planets and sun look
as "real" as possible, to contrast them with the mechanism,
I need to move further in that direction. Maybe dust and/or
scratches on the hardware might help, but it's such a nice
table :-)
I'm much less happy with the room itself, admittedly I've
not spent as much time on it as on the orrery itself.

My first impression was 'waaaw'
it has something wonderfull, it even makes me think of tomb raider in some
way. it actuates the same mood in me.
To be honest, i thought it was a shiny floor with the mechanic in the center
of the room. but when i took a closer look i saw it was a table.
mabye a larger view can fix this.
very nice overal image!! finish it :-)

Actually I'd thought darker, to kind of echo the portrait on the wall,
fading to black in the shadows.

Yes, now you mention it. I'd thought of calling the picture "God's Orrery"
but that might have caused offence, maybe, esp with the connotations of
"Gods Drawing Room", "God's Wallpaper" etc :-)
Anyway that was the idea. I just don't know what to replace it with.

Maybe, but in the planetary images I've looked at I don't see that
distinction.

well it's just an orthographic image_map onto a sphere, the main
problem then being keeping the sphere facing the camera. Of course
since the image is taken from Earth the moon is therefore facing the
wrong way, but I haven't found any Mercator projections of the moon
I could use for a uv_mapping.

Thanks very much! It's only my 3rd real attempt with Pov.

Yes, I guess I tried to go halfway between the false-color Soho type

I'll make a try for some prominences, probably some fractal approach,
I remember seeing some fractal concrete that looked close in shape,
I need to look around a bit.

An Orrery would contain all the planets, if you look closely at the
central pillar you'll see spare bands for Mercury, Jupiter, Uranus,
Neptune and even Pluto; I was thinking of running rods in various
directions out of frame (Mercury would be behind the sun) to hint
at their presence, but it might get cluttered, also there's all
the moons of Saturn to consider...
I really just wanted to get a selection of the most interesting
planets in the picture, and Jupiter lost out to Saturn :-)
As for scale, I'd tried lots of approaches: log, sqrt and cube roots
of the actual distances and diameters, none of them worked very well.
In the end I just settled for "X is bigger than Y" and left it at that.

hmm, maybe it is true colour, I'd always thought of it as a blue-ish
white though, and that has a better contrast with the other planets.

Yes, thanks for pointing that out, I'm least happy about the room itself.
I'll experiment.

Not at all, thank you for your suggestions.

maybe, but every unit I pull back the camera looses some definition
on the planets, there are some very difficult compromises to be made.

Thanks! I'll try.

though 10 may be too high, it was just my first guess.

Look here for some maps which you can
just map onto a sphere using spherical
mapping (map_type 2):
http://www.jht.cjb.net/
That could help for the moon. For the earth,
look here:

Ah! That triggered a distant memory from an art course long ago and far
away... and a search on "orrery" and "god" brought me to the original
painting. Nice allusion. Can you find a camera angle that would show all of
Wright's work? I didn't recognize it with its top cropped off.

Don't let the kids play with it, you just know they're going to swing
our moon into Mars.

That certainly is better for the moon, thanks very much.
By a strange coincidence that's the site where I got the
earth maps from, I just hadn't looked around.
