Thanks, Kevin: I tried the camera projection before I posted and abandoned it because it didn't improve the render. 

That looks much like what I have been getting. But it's still out of focus because the projected image is close to twice the size it should be. 
In the attached cropped image, I rotated Jupiter so my render shows a view of a recognizable feature - The Great Red Spot. Juxtaposed to the left is an actual image of Jupiter as obtained by the Galileo probe, also with the GRS in view. It's far smaller than the one in the render.

Reducing the image size and / or increasing planet radius doesn't seem to make any difference, except to make it worse.

I think this might be what you're after.

1. Add a new camera to the project and change its projection to Spherical.
2. Copy coordinates for Jupiter's Centre parameter.
3. Paste coordinates to the new camera's Position parameter.  This will move the new camera to the center of Jupiter.
4. Set the Image Map shader's Projection type to Through Camera, and the projection camera to the new camera.  The Position center radio button should be checked.

Here's what I got.

Terragen Discussion / Image Map Projections Onto a P...

My current endeavor is to recreate the planet Jupiter as viewed from its inner moon Io. I am struggling with the Image Map shader to accurately project an image map onto the surface of either a Planet or Sphere object.
I am relying heavily on Jordan's Night Full Moon Example Project (Stars Included) files, especially the Starfield Generator. I also used the link he provided for image map. Thanks to him for his hard work!
EDIT: The image is too fuzzy and I I have tried sharpening, but with little improvement.  I also plan to create a vapor plume somewhere near the mountain in the scene, but that's another subject...
Thanks in advance for any workable solutions!

Terragen and CG for geological science is a cool thing!
Doesn't look real, but it's a nice render to illustrate differences in nature.

Right. There is a hazard making things look too real in science communication. Folks will find a flaw in the render and then make some claim as if you were trying to fool them. My clients were happy with this level of "reality" and it was easier to create as well.
I was hoping for some animation to come out of the project but time ran out.

This is great work but I find the edges of "things" too sharp and clean.

Thanks. Any objects in particular? I can take another look. But all of the objects (such as stone blocks and wood planks) are already beveled, there are no sharp edges. Keep in mind that all of the planks are fresh from the sawmill, and the stone blocks are shaped and dressed onsite.

Sounds interesting, very intriguing project. If I weren't so busy, it would be an adventure to dive into, but I'm afraid I have to decline myself. Maybe post this on the Discord server for more views?

Cool progress, thanks for posting the drone picture.
