    ...at these ranges (>547 km and 200m), will I be able to distinguish the 2 
    separate objects? my gut tells me yes.

    I would like to take a stab at this just for fun. Using this applet 
    http://www.1728.com/angsize.htm I came up with about 1 minute of arc at 547 
    km distance and 0.183 km separation. I believe that is right at the limit of 
    resolution for human vision, and that under bright conditions. 7x binoculars 
    would be a best bet. However since atmospheric effects are a major problem I 
    think it's anybody's guess as to whether you will be successful.
