I use Xara Designer Pro, a vector drawing program like Illustrator, though it's lite version Xara Photo & Graphic Designer 365 ($49) can do this too - that's what I use to create the interior deck plans, and Hvergelmir as well. I otherwise use Wings 3D, a subdivisional surface modeler to create the models, exported as Wavefront OBJ format, imported the Poser 11 for rendering, only because it's fast. Then finish everything in Xara.
Here's an illustration, also done in Wings 3D, Poser 11, then finished in Xara, as a monster encounter in the adventure module - a Star Eater, this thing eats stellar plasma, but has a hankerin' for purfied starship plasma. The plasma it eats it can beam from it's mouth like a laser weapon and propel itself through space. It is found in a particularly empty of stars region of space, presumably this thing is eating those stars. There are also two massive black holes, also believed to have been created by this creature.

So I'm trying to wrap up the extended one-shot module I'm currently writing for publication, Rogue's Run, but I needed a planet map and globe view for where the adventure starts. Just finished it and adding it to final page layout. It's a frozen world in great elliptical orbit with 5 years of winter, followed by 1 year of spring/summer/fall. The planet is Nifliheim, named after the Nordic hell.. enjoy!

The following is the map of Rogue's Run, a smuggler's route no longer used, but the PCs in the module are forced to use to bypass a blockade to their destination. Also a hex map upon exiting the Hellgate wormhole where a corporate mine-laying vessel is creating a minefield that the PCs must negotiate to avoid triggering a mine, but will be subsequently shot at by the corporate mine layer itself. Enjoy!

Finally, finished writing the module, making all the maps. I just have to stat up 2 NPCs and I'm done with Rogue's Run. Though I posted one version of Port Carthage Asteroid Station, I redid the maps as a more underground tunnel system city, instead of a rectangular city stuck into a cubical void in an asteroid. I like it better. Instead of creating interior spaces shown, I did it more like buildings like a city map. Enjoy!
