Congratulations for this great software.

I would like to do a little movie with the rotation of Venus.
To do that, I put the observer location in the Sun, center on Venus, increse the zoom, and accelarate the time.
But in this situation the planet start shaking, as if the "camara-men" can't track the planet softly.

Is this a bug?

Best regards

I see it too, when looking at an object from large distances (1 AU and above), and zoom in too close.

I've investigated this somewhat, and I suspect that the problem is related to the fact that all consumer OpenGL drivers and hardware use single precision arithmetic internally. The limited precision manifests itself as a jitter when the field of view is sufficiently narrow. Unfortunately, this means that there's no easy solution to the problem. A better way to make the movie would be to move closer to Venus so you don't have to zoom in so much.
