The TT definitely cut mirage a hair better. Not some wild amount, but it was enough to notice. The ZCO and the Kahles handled mirage the exact same to my eyes. CA differences were negligible between all 3 of them in my eyes. I still stick to my original take that the Kahles is a brighter optic period than either of the other 2. The ZCO had a darker shade to its image and that does help a little in color separation I think. At least to my eyes.Did you notice any difference in mirage or CA?
