That is my question, the biggest I have seen is 8x30:

I guess it depends on what you mean by "biggest." Bushnell makes the Natureview Plus in 8x30, like the Orion you posted, but also a 4x30 wide angle that gives a 900 ft. FOV and therefore a "bigger" view with the same 30mm objective.
I would like to see an RP design w/ a 32mm objective made with the same quality as the Custom Compact Elite E2......
I believe that Bushnell made a really big one that many people, like me, mistook for a Roof Prism. It was an 8 x 50 or so, if I recall correctly. Some one should come up with it, bye and bye, I'm sure.
