Although the maps that he's published are static images, they give the impression that they're screengrabs from an interactive information display system.
With his permission, I've implemented a simplified version of that system, using Celestia as the platform.
V1.0 of my adaptation now available. Ilanthar posted that he won't be producing the next map in the series until October or so, so it seemed appropriate to tie up some loose ends and finalize this version. I'm hoping that it'll be possible to add future maps without people having to download this entire Addon again. Note that none of the maps that I've used are my own creations, although I've modified some of them. The initial map of the Milky Way, for example, was obtained from NASA's Jet Propulsion Laboratory.

If there are any features that you think should be added in v2, please don't hesitate to let me know.

This Addon is designed for use with Celestia v1.6.1 or later. It will not work with earlier versions of Celestia. It seems to work fine with preliminary builds of v1.7.
If you restore from this Zip file into Celestia's "extras" directory, it should recreate all of the directories and files necessary for this Addon to function. Be sure to read its included "readme" files for operational instructions.
Here are a couple of screengrabs.
Here's the opening screen:
and here's a view of the Hyperion planetary system:
