I try to make true skies in the Bryce 7
did you make also?

Excellent! Did you know that the Custom Stars are the 6000 stars we can see with the naked eye in a dark night?. Set the camera to look north (up, when looking from above) and you get the stars of the northern hemisphere at the spring solstice.
Thank You Horo.
The problem is that Castom Sky is not rotating as we see the daily rotation of the stars. So we have to force to rotate the camera and its associated group of objects (the horizon and a spherical mirror) as the our planet rotates.
You can move the roller ball but this is rather arbitrary. We've asked for numerical input during a dev cycle but we haven't got it. Another thing we're missing are nebulae, the Milky Way and things we can see with the unaided eye.
I would like to achieve not arbitrary, but realistic motion of celestial objects - for projection in the planetarium.

Yes, such animated sky objects are very nice. Jupiter was quite impressive, thanks for the link.
Also thanks for sharing your setup of the above render. This is not a hemisphere look but a mirror ball look. There is much more than a hemisphere because a mirror ball shows everything that's behind it towards the perimeter. There is a way to limit a mirror ball to just show a hemisphere (like a circular fisheye lens looking up). With your Bryce 7.1, you should have got some content and tutorials as well. If you can locate mine - content\tutorials\Horo Wernli\ look at Hemispheres. There is also DoubleMirror.obp which only reflects the hemisphere. Perhaps it helps.
Just a throw away thought, could you not composite the sky from another source with the Bryce generated mid/fore-ground layers? For example, Stellarium (http://www.stellarium.org/) is a free planitarium app that supports scripting and can be used to produce animation snapshots.

Yes you could, but as Bryce doesn't automatically generate alpha channels, you'd have to do your animation frame by frame with each frame also rendering an object mask and then use the object mask as your alpha channel in a photo or video editing application. Or run your animation render and then another animation render of the object mask sequence and use a video editor that allows the use of layers.
It would also be much easier as long as the camera didn't need to move as programming Stellarium to sync up with Bryce camera movement wouldn't be simple.
