From my primitive understanding of Maksutov optics that seems to make no sense. You should see it off center inside or outside of focus. Fiddling usually leads to trouble. Maybe you should contact Orion about the problem. Most Maksutovs do not allow for collimation. I am not familiar with this Orion scope so I cannot specifically advise.
