Hmmm, that latter comment makes me wonder if there a difference in stray color dispersion in the AK and SP roof prisms.
...or something else in the total design used with the AK prisms which lends itself more towards CA. The full sized Conquest ABKs display noticeable CA in comparison to the full size FLs though the mid size Conquests do not.
Also, I wonder if your comments with regard to glasses and the Cascade porros might not be the issue. I can force myself to see it if I off center my eye in the eyepieces but otherwise I really have to look for it to see it.
