Have you seen the interactive Galaxy Map for 40k?
Looks well!
Couldn't figure it out after 30 secs - irritated.
There are very few locations, and there's nothing for koronus or calixis, so it's kinda useless, even though it's pretty.
They have Kornorus Planets and Calixis, I found the Lathes and a few world in the Korornus "west" portion of the map...
Really cool, but doesnt seem to find any of the "important" sectors or places, so thats too bad
