The corrector plate on a Mak causes the light rays to diverge, meaning that the primary mirror must be larger than the corrector plate in order to retain the full aperture. It is well known that the Synta Maks use a primary mirror that is the same size as the corrector plate, which is the cause of their reduced effective aperture, while the JOC Maks use a primary mirror that is larger than the front corrector. We know this because people have taken their telescopes apart and measured the components. Well you best tell every supplier that they have got it wrong.
