believe it or not the Meade Series II Orthos are even better than the RGs.
Not the ones I have. My RG Orthos are from 1979-1981 and are far superior to my newer (late 1980s) Series II Orthos.
In all my years of observing I haven't seen any Ortho be far superior to any other. All the differences I've seen have been subtle at most. A little more contrast, a little less light scatter,a hair sharper, etc.
