I wonder how this changes if at all the central 50mm or so of light cone. The older Celestrons are great for planetary imaging, but not great for DSO photography. I have not seen many hi res images of the planets with the Meade scope as they currently stand and as a result I would hazzard a guess that the light cone is slightly soft around the center. Mind you it might just be a case of people not using Meade scopes generally for planetary imaging. The best situation would be that one could do planetary at hi res and DSO's with lovely flat fields and sharp detail.
My only real gripe is the corrector collecting dew. It is bad enough for an RC8" but using a dew heater can totally wreck the quality of the images that the optics would potentially hold.
I saw the HD scopes being made in China. I did not see how they put them together but the mirrors look like standard sphericals to me.
