At optical infinity, e.g., stargazing, it provides no benefit at all. For birdwatching ≤ 200' it can be highly beneficial for localizing and making size/distance estimations". So he agrees with you Troubador<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" /> but them I asked him this and haven't gotten an answer yet. Ok, just talking about stereopsis say we have a Habicht Porro(Good 3D) and a Swarovision SV(Poor 3D) and we are looking at a mountain valley with a river in the front of it at a distance of about 1 mile away. There are some objects that are closer in the bottom of your FOV. Are you saying that the view through the Habicht will be just as flat as the Swarovision and have a complete lack of stereopsis. I have a hard time believing that in a view like that you wouldn't still notice some 3D in the Habicht. I just think in distant terrestrial viewing you are going to see some 3D effects even at quite a distance. But I am going to have to test it. The jury is out on it for now. For now I agree with you. Also, Troubador thanks for watching over my thread why I have been busy. :t:</blockquote>
