Just double check Paul. Can't hurt. Trust me on that one. I took so may things for granted when aligning my C11 like the cut hole in the corrector glass being centered or the secondary being glued centered on its aluminium block. Both weren't. The corrector cut hole glass was off by no less than 3mm. Just check it again. Doesn't take long then you can take that out of the equation and work your way forward by elimination other wise you'll go in circle and get more confused
