I want to see the 120 or 150 Synta resolve craterlets in Plato with
that there chramcore thingy...

I've seen some images taken by Tom Davis that does show this kind of detail,
with and without the "thingy". This "thingy" does not necessarily increase
resolution - that is strictly a function of the aperture size as every amateur
should know by now. All it does is to re-focus the defocused energy in the blue
end of the spectrum so that the image overall is closer to that of an apo (the
blue is brought to the same focus as the green and red). Without it, only the
green is in critical focus, both red and blue are defocused.
