The problem with that is I don't have another Chinese ED 10x to compare it to. I suspect that stray light issues dropAnother issue with the 10x is I don't see the whole field when wearing my eyeglasses which I do with birding. In fact, not wearing them negates the effect of the really good bins i.e. not correcting my astigmatism gives me a noticeably worse view even in the good eye that has only -0.75D of astigmatism. This is a little like the Hawke 8x in which I just don't quite see the whole field. That means that I don't actually see the halo when birding. I only see it when testing (and I took off my eyeglasses). I'm also not 100% sure of the repro case for that problem.But as you want some sort of an answer here's a preliminary result. In the "close to the sun" stray light the ZR 10x seems to do very well. I took it to within about 10 degrees (really that's as close as I dare) of the sun. You can see bright but not brilliant crescents on the opposite side of the image to the sun but the veiling glare (reduction in contrast across the field) is rather small. The view is still usable (not as good as in the opposite direction of course but you could get a bird ID this way). With the Chinese ED 8x I get to this point at about 20 degrees.If my idea about this kind of stray light being related to the width of the FOV of the EP then a 10x is going to be better than an 8x in this kind of test. Anyone out there with 8x and 10x of the same bin can try this sort of test but be VERY CAREFUL when close to the sun. Seriously, you know the risks of doing this (and if you don't don't try it).But it still needs more testing especially on the 8x to say anything definitive about if this is better than the Hawke or not. My null hypothesis is that it will be the same (the rest of the bin so far seems to be the same) but I need to actually test that speculation.</blockquote>
