I have the same issue right now. I am fairly sure I hadn't have any problems regarding the galaxy fiew when rebellion launched. I created a custom ingame map maker with 10 stars and about 180 stellar objects. As soon as I zoom out of system fiew every map icon disappears, leaving me without even the slightest indicator of where my units and the stars/planets are - explored and unexplored alike. It won't even show the galaxy-like "whirls" that would indicate that there's a system. Only when I hover my mouse over a really tiny spot while rotating the view in an absolutely arbitrary angle would the planet icons pop up.
I am running the game on a notebook with i7-3840QM processor, 16GB DDR3 RAM, nVidia GForce 380M with latest drivers and Win7 64bit OS and I did the usual troubleshooting including several restarts, running in windowed mode and messing with major graphics setting.
On launch date I still had an inferior notebook with AMD Radeon graphics card and no issues so it would seem likely that this as something to do with nVidia drivers.
Seeing how long this problem is floating around already I doubt this will ever be fully solved but if I could provide any help with posting my system specs please let us poor emperors know of any progress because this issue makes being galactic emperor and commanding your loyal minions a real pain ^^
