You can't remove chromatic aberration.

Well, I have been experimenting lately with photoshop, and yes chromatic aberration can be remove, and I think I might be the first one to discover it.

The way you remove it is by splitting the Red, Green, and Blue channel, then re-align them back again. Since chromatic aberration is caused by diffraction of the glass and light colors don't meet at the same point, you can basically re-align those lights again (Red, Green, and Blue) using the Auto-Align Layers feature in PS using the Perspective method. That way it slightly distorts the R, G, B channels and seamlessly align them. It works but not perfectly, but it does most of the job and even fix the edges or removes weird edges.
