Your photo shows that yours is a fork-mounted alt-azimuth telescope. You may find that the additional length required to accommodate 2" instead 1-ΒΌ" eyepieces will result in the eyepieces smashing against the base and prevent you from viewing objects near the zenith or anywhere more than a limited number of degrees above the horizon.

You could get a 2" SCT diagonal and then you wouldn't need a visual back. Screws directly to the rear cell of C8.
