I'll add that not all 1.25" diagonals allow the light cone to pass without vignetting. The Everbrite is a good choice for that reason - it's designed to work with TV's maximum TFOV eyepieces such as the 24 Pan or 32 PL. It replaced my WO Dielectric, which added a fuzzy black vignette just inside the field stop in those EPs.
With a 90° diagonal already in the mix, it would seem most economical just to leave that out at low altitudes and observe straight-through, with the added benefit of an even cleaner image (at least on paper).
