The thing is that a GSO 12" mirror is about the price range of the achro,
so my logic is we should compare it to that. Zambuto quality is not fair...
I think the average 12" and the achro will top out at 200 mags.
The mirror is because the lack of figure and polishing, the achro is too
fast and possibly not well corrected. Still, 6" and no obstruction....

You will see more detail with the 12" (if the seeing allows) central obstruction or no.

Portability, cool-down time and convenience are other important considerations though.
