If you do dismantle it, it is very important when reassembling to maintain the orientation (ie rotation) of the corrector with respect to the primary mirror, and the secondary mirror with respect to the primary (or corrector).
Look carefully for a small mark around the perimeter of the corrector and another on the secondary or its cell and these should line up with one on the corrector cell; typically its a line or "V" mark in pencil, or in a dab of black wax on the edge.
If you can't spot such a mark, put a piece of tape on the OTA and a corresponding mark on the corrector and secondary.
