Different prism design spotting scopes. (1 Viewer)

Hi,

As Im looking for a new scope Ive started thinking more about their prism layout.
I've noticed a lot of Kowa scopes have the eyepiece offset to one side, while others don't.

Many thanks for your time and help
John

I've read that. But I don't think it tells me about the layout of Kowa's off angle eyepiece, compared to opticron/celestron etc

For anyone who cares I worked it out myself. In the kowa scopes the porro prisms are on their sides, exactly like one half of porro Binoculars.
