I agree. This is very true. If all one looks at is the central 40 degrees of AFOV than a *good* Abbe Ortho is as good as just about anything out there...excepting a better Abbe of course
But I think this trivializes the importance of AFOV and ER. IMO Optical Performance, ER, and AFOV all come bundled like three legs of a stool. Cut any one leg off and you potentially have a "specialty" stool. So when people ask advice or there are discussions, all three really have to be considered and weighed together as it is the whole package that is required for observing.
I have wide fields with nice ER, and I have *good* Orthos. When I try to observe with just the Orthos, after a few sessions I try a wide field and realize well why I would not want to be stuck with just Orthos as my observing eyepieces. Then when I observe with just wide fields, after a few sessions that involve lunar and planetary, then I realize why I would not want to be stuck with just wide fields. In my course I have realized that for me, they compliment each other rather than compete. The DeLites though, are IMO the first eyepiece that seemingly *starts* to bridge that gap.
