The Chinese computer generate a lot of their optics these days. No surprise optical quality wise for a reflector as they are doing a stand-up job by mass produced standards for both types. (I own a Celestron C-6R [Synta optics] 6" achromatic refractor. Computer generated lenses with near text book diffraction patterns 4mm eyepiece with Sirius as my diffraction subject
An excellent mirror with enhanced coatings and a dielectric coated secondary should beat even Apochromats (relatively speaking) because of shear workmanship necessary to produce a quality Apochromatic lens capable of the same light grasp as say a 12.5" f-7
But then again, when I first saw Saturn with a 7" f-8 APO at the Miami planetarium I did the "Is this for real?" double take at first. The image was almost flawless with NO CA at all..at all.
