The standard resolution test procedure is just one of countless possible tests....hence the amount of time I have spent devising other tests for the Habicht.If Henry and others question the Habicht due to its results in a simple two dimensional black and white bubble jet printed resolution chart, then I must likewise question the performance of otherwise excellent alpha binoculars when they simply cannot resolve a single length of shaded translucent spider or worm thread, when the Habicht can. Can we devise a simple and repeatable version of this test in which others can likewise rank and file binocular performance?Also, I must wonder if certain folk can be less compatible with a certain instrument. A highly complex interaction is taking place between human, binocular and target. If we want to become excessively analytical and  reductionist, which is what happens sometimes with myself and others, then should we also be asking what biological profile the viewer has, including full eye function and all possible (and often unexpected) medications which can impact the viewing and brain/eye function (which can cycle in a 24hr basis)? I know about this first hand, from using myself as a guinea pig.Perhaps we should also be asking if a two dimensional resolution chart is an appropriately challenging test? Is it just too overly simplistic compared to the inherent complexity of viewing in nature?I still think Henry got a lemon <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" />Cheers,Rathaus</blockquote>
