A true Ritchey Chretien uses a hyperbolic primary and a hyperbolic secondary mirror, with "NO" corrector of any description. Importantly, the curves of both the primary and secondary mirrors must be perfectly matched to each other, to optimise optical performance.
As others have said Meade's claims as to an Advanced Ritchey Chretien telescope is pure advertising hyperbole. Only 1 of it's 3 main optical components match that of a true Ritchey Chretien. That being the hyperbolic secondary. That doesn't mean it isn't a good telescope, it means it isn't a true RC.
True Ritchey Chretiens 5, Meade 0, but who's counting
