OK, will accelerate process little bit: lets put together (on drawings only by now ;) )
Apply tilt to your LNB 22,6*, as this angle will ensure your system best X-pol characteristics (want to know about this more, look Mizugutch feed axis tilt or Mizugutch condition). Place LNB in such way it does not obstruct signals (green lines on my drawing). Now you can clearly see dots "a" and "b" where green lines crossing red lines (representing illumination angle of LN. Move LNB left-right and up-down to find proper position of F2 to get distances F1:a + F2:a= F1:b + F2:b. Than draw an ellipse from F1 and F2.
