Owning a pair of Parks 15x80's, which aren't really BIG, but you wouldn't
take them to the opera<g>, No, there is no true stereo effect from
lunar/sky viewing, but since collimation isn't (can't be) perfect, and
they don't have a truely FLAT image plane, they definitely seem to give
a stereo effect. I know its not 3D, but it SURE LOOKS 3D!
Use the for terrestrial viewing and there is a strong 3D effect.
