I see Meade is in the processing of releasing a new version of the good, old LX90, this time with ACF optics...that is, the same prescription as in the LC200-ACF (nee LX200 R).

Are the ACF optics easier to fabricate than the SCT optics? They still use a spherical primary but now the secondary is hyperboloid(?), which would be more difficult than the spherical SCT secondary. How is the corrector plate on the ACF relative to an SCT corrector plate as far as fabrication goes? Success in the business is being able to run these things with minimal hand work.
