This is totally sweet! I usually get too wrapped up in playing the game to "seriously" mod :P
I'm still working on completing my first mod lol
I did some work on celnav a while ago, and my sky always seemed to show up at GMT=local (I haven't followed what all has been said about the clocks, I hope that Reaper has "fixed" that little oversight)
I shot all my elevations using the observation periscope after discovering that I couldn't get my MaGui sextant to work (I think my screen buggers the angularity somehow...)(or it's just that pesky 5:4 v 4:3 problem)
Either way, I'm really stoked about your inventiveness and investment of time on this project!
