Henry,
Thanks for your observations. I was looking at the OPs photos in the wrong way. I see now that his photos show the CA only at the edge of the NL image. I had thought incorrectly that where the CA was obvious, it was at the center. With a large flat FOV, your eye has a difficult time seeing the edges without forcing your eyes to either side while viewing. It's a bit uncomfortable for me to do that, when focusing on subject matter in the center 80 percent of the view. Perhaps, that's why I don't see CA, at all, with my NL's.
