If it's atmospheric dispersion it would require good optics and a long focal length for it to be visible - so I'm not surprised if it doesn't show with the f/6.3 reducer.

 

It is all consistent with dispersion but it may be collimation.  Both things are easy to check.

So if colors are always on a line pointing to the zenith, it is AD and if it stays the same relative to the camera, it is collimation?
