Yes, indeed 24mm at 8-24x Baader zoom has 48deg FOV, but that's not too much difference from a standard plossl (~50-52deg). But I've found that a pair of cheap Celestron Omni plossis 32mm work excellent for DSOs.
I had to switch to 1.25" Baader prism diagonal (with a 2" nosepiece) to save some backfocus as with a 2" mirror diagonal I had only about a few millimeters of backfocus and it was way too heavy. It worked, but with 1.25" prism it's much better.
Here is my setup (from right to left):
SWBD100ED - 2" ClickLock (#2956256) - 2"/T2 Nosepiece (#16/#2408150) - T2 Prism Diagonal (#1C/#2456005) - GPC 2.6x (#4C/#2456317) - T2 Changer System (#06 & #07 #2456321) - Binoviewer.

However, I'm planning to add ADC in the future so I'll have to move GPC to the front of the diagonal to save optical path even more and to eliminate any possible spherical aberrations in prisms.
