What I mean is, that, at present, you could be firing at a 45' angle to the sunward edge and still have your targeting systems interfered with. This seems completely unreasonable outside the Flare and Mercurial zones - the star simply isn't that big or dazzling.
What I mean is: keep the double shift, but restrict it to the flare and mercurial zones, where the star really would be large and bright enough to interfere across a wide angle.
