1. Assume R = 1AU = 2AU.
2. Place your camera in a fixed position anywhere in a sphere of radius 1AU centered on the Sun.
3. Point it at the NCP. Chock the shutter open. Rotate the camera 360 deg in almost any period of time. Close the shutter. Result -- star trails centred on the NCP -- sometimes referred to as 'nightly' star trails.
4. Point your camera at the NEP. Chock the shutter open. Rotate the camera 360 degrees in almost any period of time. Close the shutter. Result -- star trails centred on the NEP -- sometimes referred to as 'annual' star trails.
5. In #3, the rotation can be obtained by fixing the camera directly to the Earth.
6. In #4, the rotation can be obtained by fixing the camera to the disk of the ecliptic (or by simulating it).
I wanted one picture of the wedding party and one of the bell tower. You've given me two of the wedding party.

That's the whole point, Jack. There is no difference. Yet one simulation is achieved with a snapshot every 4 minutes and the other is achieved with a snapshot every 24 hours.
There is only one rotation axis, not two.
