I don't really get this with lateral CA, how it works. What I do know is the fact that the different colors focus on different distances from the optical axis, causing fringing. But I don't get that they are getting magnified differently. If we shoot a star at night, will the red light from the star have different magnification than other colors, causing the red star to be bigger or smaller than, for example, the blue star? My view is just that the colors are the same sizes (magnified the same) but just the fact that they are shifted differently along the image plane causing fringe. What is wrong in my view?
If you would have used an RGB camera you could have shown the actual color shifts. That last test, zooming in and trying to show differences between R, G and B, results in three about the same images because of the the auto-exposure. The auto-exposure filters away the color shift affects because it creates the same amount of grey for each of the three.

Woah, beauty and brains. Watchout.
Thanks

What could be the cause here? flic.kr/p/2jcHUM8
I don't think it's defocus aberration after some thinking.
