The ACF system differs from non-ACF with a coma corrector built into the baffle tube of the ACF tube.
Not sure this is correct.
The Celestron edges have a corrector in the baffle tube
but the Meade ACF uses a non spherical secondary, and IIRC, a slightly different figure on the corrector to flatten the field.
