Anyone know what the field of view is if you can see all three stars of Orion's belt through Binoculars? ( 9x 63)

Orion's belt stars are only 2.75 to 2.8° across, not 3.3

My PDA program, 2Sky, calculates the distance between the outer two as 2°44'10". I think the signficance of the distance would be that this just about represents the lower limits of what one can readily use as a FOV without a wider angle finder. The lightweight 23x90 that Bill Burgess now wants to make, for example, would likely end up with a field of view right around 2°49".
