Thanks Kevin for that CA chart from Don Pensack - very useful! It seems from that chart that the 102 would be in a preferable CA zone, but from what you said in the other thread the CA for visual DSO work on your 120 is okay?
I am definitely NOT looking to go high power planetary on this scope - the max I might ever push it is my 9mm Nagler at 67x for the 120 mm (57x for the 102).
