The "basic effect" is simple:
Paul, you're talking nonsense.
The apparent speed of an object crossing my line of sight,
is like Vapp=Vo/(1+cosµ.Vo/c) where µ is the angle that the direction of the object makes, and the direction of my aim.
If this object moves towards me, then cosµ=-1.
As Jean-Pierre Python rightly says, who for once is not mistaken, we obtain v_app=v/(1-v/c)
In Hachel writing: Vapp=Vo/(1-Vo/c)
We want to know at what speed the object must move so that its apparent displacement is equal to or greater than c.
Vo=Vapp/(1+Vapp/c)
If Vapp=c or more, Vo>c/2
