You'll be able to get it to work Vincent, it's just a matter of finding the right combination of diagonal and barlow/corrector.

If you're using a 2" diagonal you could try a 1.25" diagonal which chews up less back focus. A 2" GSO barlow element screwed onto the nose of the 2" diagonal might work. A short 2x barlow instead of the 1.6x supplied corrector could work. You could try screwing the supplied 1.6x corrector onto the nose of a 1.25" diagonal.

EDIT: actually a long 1.25" 2x balow would give a lower magnification than a short barlow, but be careful that the barlow doesn't bottom out on the mirror.
