there is one of these for auction on Astromart. There is some discussion on Cloudy Nights as to how the mirror and corrector are figured. Some say they are all spherical. I doubt it because of the reviews I have seen of the scope. I doubt an all spherical system could perform that well.
would you mind providing comment?

The 10" Mak-Cass is not an all-spherical system. It has an asphere on the primary mirror.
