I'm just uploading some load screen bmps and if they are done in time I will merge the custom load screens into the mod. There will also be an alternative Earth night sky package too, so all is coming along very well.
Great! Well I found a couple of mods that might help, unless you've already got something:
http://www.tesnexus.com/downloads/file.php?id=15427 has some real star cluster/galaxy textures for the sky; you could probably find some nice ones in here to use. Some are a little busy, but I think there is a Millky Way sky texture in there.
http://www.tesnexus.com/downloads/file.php?id=15136 has a good Earth Moon texture, I believe (as well as the Death Star, Borg Sphere and many other things you wouldn't want to use for this

). You could use the Moon texture for Masser and then either blank Secunda out - or maybe even a better solution would be to replace it with a specific star or (tiny image of a) planet/galaxy (andromeda maybe?)
There is even a http://www.tesnexus.com/downloads/file.php?id=19925 mod that changes the night sky at intervals, so you could have the visible constellations change seasonally or something like that.
Anyway - I know you've got your hands full with Mesogea as it is, but just wanted to give you those resources in case you need them!

I will upload the mod for about one week before releasing it publicly as another member has offered to do some horse seller NPC's for towns and so forth so tourists can quickly join the Imperial Post service and get a horse at each staging post, much like the Roman system.
Cool - That sounds good. Horses that actually
tire eventually would be pretty realistic. After all, horses are not really meant to ride at full speed for miles and miles and jumping up mountainous slopes, etc. without tiring (they can even die from exhaustion). So the horse-post thing would be pretty cool. They could make it where actually
buying a horse is pretty expensive while renting one is economical, especially at low level. If you rent one then steal it, it could behave much like the vanilla horses; it starts walking (or even running) back to it's point of origin on it's own.
