Unfortunately we cannot support zooming out to Pluto, as we would also be forced to support zooming out to Eris.
In the meantime, this will probably help:
/console CameraDistanceMax 25
/console CameraDistanceMaxFactor 2
If you feel like returning to Earth, or encounter difficulties with your zooming spaceship, the following commands may be of use:
/console CameraDistanceMax 15
/console CameraDistanceMaxFactor 1
Just type them into chat and you'll be all set!
