Any help would be appreciated

Hi Tezza,
Welcome. Nice scope (I have one), but I think you must have been misled. The Megrez apo WILL require an extender for your eyepieces to come to focus. A bit of a pain, that.
Williams Optics sell them, of course, but BINTEL have them too, and although not as shiny, they are cheaper and probably do the same job. (You will need the 50 mm one, if you get it from BINTEL. WO's own are 55 mm, I think.)
Good luck,
Brian.
