Not all Maksutov-Cassegrain designs are the same as the secondary could be an illuminated spot on the back of the meniscus or a separate mirror that may or may not have collimation screws. Special (factory) equipment or techniques may be needed to collimate the optics if they should ever require it and this may only be if heavily bumped.
