Besides the stock NASA stuff, you're kind of left to create your own.
If you have moderate skill with ModViewer and a paint proggie, here's what you can do.
a) Load a planet in ModViewer from SFC. Get it the right size and take a screen cap.
b) Pull in into a paint program and change all the VB-like blue to black. Save.
c) Load a ship into ModViewer. Arrange it so that it looks solid, no holes in the shape. Cap.
d) Change the blue to black. Now you want to select everything except the ship.
e) Go back to your planet. Copy. Go back to your shape. Paste into Selection.
f) If all goes well, you have a planet behind your ship.
There are other ways as well, but this is a good basic method.
Or try Universe and/or Terragen...those are good tools as well..
