Hi Charles,
Take your 8x42 to a store, or stores, that sell the top of the line Leica Ultravid, Swarovski EL, and Zeiss T FL binoculars. If you can, also try to find a Nikon 10x42SE or 12x50SE. Maybe the Nikon Prostars if the store has them. You could add the Canon 10x42IS and 15x50IS to your list of fine binoculars to have a look through. Compare them to the view through your 8x42. This is easy and inexpensive.
Looking through these high end binoculars will give you points of reference to use when looking through other binoculars. look for things like resolution, contrast, color saturation, brightness, edge sharpness, and width of field (AFOV & FOV). Also, see how the binocular feels in your hands and how comfortable binocular is to look through. A good binocular feels like you are looking out a very clear picture window that happens to magnify the view by 8x or 10x.
I'll let other folks handle the question of "out of whackness".
Good luck,
Rich
