    Ryso585, this is not even criticism at you, just seeing how people believe the wrong thing, I am getting it straight. You may consider adding an explicit note in the description or the save itself.

    People, this SAVE IS MISLEADING! This is NOT how actual satellite dishes work. A real satellite dish has a parabola, not a circle. A parabola is the shape you get if you graph the function f(x)=x^2. This, while it seems similar, is NOT a parabola, but rather a piece of a circle, and thus does not really focus the rays on the focal point. Some of them miss.

    The actual circle center is at X:205 Y:200

    The circle centre is about 2 pix too far to the right

    Just realized this is how satelites work!

    mrboom: I know they are different. A parabolic antenna is described by a parabola, this one is just an approximation. I am working or a real parabolic antenna, that's why I posted.

    @Ryso585: Good work...

    @lare290:In a real spherical mirror, the rays also do not all pass through the focus, especially the rays coming from regions farthest from the central axis, there is always a slight distortion. That is why preference is given to "parabolic" mirrors, which suffer less from this problem.

    it is not perfect. it doesn't focus to the focus point from the edges.
