I'm not entirely sure which planet to use for Orion (Prime or Delta) or Sirius (A or B), but I've gone with Prime and A as a guess. I plotted the coordinates on a graph in Excel and calculated an average for each X and Y, but the x-value seemed a little off-centre, so I corrected the average based on the fact that Rigel and Emerald had identical x-coords.

(I'm only guessing here at the moment, but don't want to ruin things if you've not found the portal yet)
So, am I right in guessing that Riftspace is located somewhere around sector -2190, 0, -1675?

If I'm wrong, are there any hints you can give me about how the circle center is found? I've read in the strategy guide that there's more to it than just averaging coordinates - do I have to build a circle that passes through all six planets, and then find the center of that circle? And if that's the case, what method did you use to work it out?
