The Meade 8" LX90-ACF Advanced Coma-Free (ACF) optical system takes all of the features of the Meade SC models and then ups the ante. With it's technologically superior optical design, ACF gives a flatter, coma-free field of view with pinpoint images all the way to the edge of the field, rivaling Ritchey-Cretien performance at a fraction of the cost. ACF is the perfect solution for the serious astroimager or visual astronomer looking for observatory-class optics.
Note: Recently, Meade Instruments implemented a cosmetic change to the optical tube portion the 8" LX90 AFC and SC that brings that product in line with the styling of the 10" and 12" version.
As a consequence to the new tube design and balance point, the tube must be stored in a nose-upward position, as there is insufficient clearance to be stored between the forks. Therefore, any aftermarket hard cases, such as the JMI case, will not accommodate the newer design.
