You are bang on there Peter , .
the differance in image brightness between my 1971 60mm Meade refractor and the 63mm of my Zeiss Telementor is quite a lot at the eye piece , easily seen .
only 3mm .
Fun on a good night mate I enjoy a evening using my refractors on the 5-8 day old moon
. I view with my small scopes more than the cannons , ,5 miniute's up and running ....
same in reverse at 2am
Jupiter looks good right now ..
in my 63mm. at 93x .

I think the 9.25 is a great scope, but I think its reputation exceeds its reality a bit. Yes it is a *little* flatter than the C8 or C11, but nowhere near as flat as the Meade ACF or Celestron EDGE HD scopes. The only advantage I see it having is weight, I think it is about 2.5kg lighter or so.
Not sure which is easier to cool down to ambient temperature.
I also have a celestron C8 and the M10 gives way better images on planetary. I haven't had a chance to side-by-side with the C11, I would be interested in seeing how it compares, as it has the hyperstar option for DSO work, and is a large enough aperture to put a decent camera on it.
They are all great scopes.
