It appears to me that this scope does a reasonable job, seeing 6
diffraction
rings at high power is a sign things are pretty good.
???????
I've never seen that in a scope I consider good and am not sure why I would
want to. To see 6 rings means a lot of light is being pushed out. IIRC, S&T
had a discussion on this years ago about some older (uncoated) scopes that
did this with (?)multiple reflections between r2 and r3(?)
