My 10" GSO is the same way - doesn't have enough in-focus for the Digital Rebel.
I overcame it by using a bino-viewer's trick: put a shorty barlow in front of the T-Ring.
That pushes the focal plane out so that you can reach focus.
The obvious problem is that I've now turned my F5 scope into an F10 scope - but its better than trying to figure out a way to move the mirror up the tube a couple of inches!
G'Luck!
